Here is the story of what happened to Trash-Chan and Tanaka-San when they went to get ingredients. I was only told about what happened between the two of them afterward. I can't guarantee the accuracy of what happened, but I will tell it as I was told.

Trash-Chan and Tanaka-San ran out of the room. They got to the store in a matter of minutes and were able to get back into the school while carrying bags of the groceries I had asked them to buy.

"We were able to get that in no time!" Trash-Chan said gleefully.

"Yeah, I'm glad they had everything we needed!"

"I'm just glad they didn't kick us out, Otaku-Kun."

"Trash-Sensei, I didn't mean to get us in trouble!"

"You started freaking out about that waifu as soon as we walked in!"

"I couldn't help it. It's not every day you meet an S-tier waifu at the store."

"You didn't have to run up and awkwardly ask her for a hug, though."

Apparently, upon entering the store, they encountered an S-tier waifu. It was some wolf-girl who was an expert with finances. When a business was struggling, the waifu would come in and help them get back on track financially. She was in the market they went to for that exact reason.

As soon as they entered the market, Tanaka-San immediately ran up to the waifu and began to talk her wolf ear off. He settled for getting a picture with her, which Trash-Chan was made to take awkwardly.

They entered the school ground. The whole place was full of people walking around and exhibits set up by the students. The school's front doors had too many people going in and out, so they decided to go around the school building to enter another way. The school had a door on its sides that could be accessed if needed, but the path to it was roped off for the festival.

Trash-Chan and Tanaka-San decided to jump over the ropes so that they could enter the side doors. Even though they shouldn't have, they could have gotten through quicker, even if they had to push through the crowd. I mean, we were struggling while we were waiting for them.

I'm getting off track from this story.

Trash-Chan and Tanaka-San were able to clear the ropes quickly. No one thought anyone would try to go in a roped-off area after all. They happily began to stroll to the door when a shout caught their attention.

"So, are you the Trash waifu I've heard about?"

They turned around to see a waifu.

"Who are you?" Trash-Chan asked.

"Hmm, so you have no idea who I am?"

"None, nice to meet you, but we need to get going."

Trash-Chan went to open the door, but the waifu grabbed her by the shoulder and threw her onto the ground. Trash-Chan dropped the bags of groceries on the ground before she was lifted and thrown. She rolled on the ground as she hit it and used the roll's momentum to stand back up.

"Oh, you're not bad," the waifu commented in a snide tone.

"Should I know who you are?" Trash-Chan asked.

The waifu wore a black leather costume with blue highlights. The uniform looked like it was a leather jacket and pants with speakers on her legs and wrists. She had long black hair and star-shaped glasses on. A bass guitar was strapped to her back.

"Trash-Sensei, she's Amplifier. In her source, she's a hero who fights for justice." Tanaka-San yelled to Trash-Chan." Trash-Chan made an understanding nod.

"I don't have any idea who that's supposed to be!" she declared to Tanaka-San with a thumbs up.

Amplifier sighed.

"I was told you were dumb, but I didn't know it was this bad," she said while shaking her head.

"Hey! At least get to know me before insulting my intelligence!" Trash-Chan snapped back.

Amplifier didn't reply. Instead, she lunged forward to deliver a punch to Trash-Chan's stomach. Trash-Chan pivoted on her heel to avoid the blow with a slight turn. Amplifier stumbled forward, having not made any contact. She recollected herself and stood straight before turning to Trash-Chan.

"I suppose you at least can fight. Please try to keep me entertained somewhat."

"What do you want with Trash-Sensei?" Tanaka-San yelled to Amplifier. He set down his groceries and put his fists up.

"You should stay out of this, little boy. I am only here to deal with this Trash waifu."

"Trash-Sensei, she knows several martial arts and fights with soundwaves at midrange!" Tanaka-San yelled to Trash-Chan.

Amplifier sighed and shook her head, then she smiled and looked at Trash-Chan.

"Well, you wanted my name. There you have it. It doesn't do you much good, though."

"I really have no reason to fight you, and I have perishables in the bags that I really should get in a refrigerator." Trash-Chan walked over to the groceries, ignoring Amplifier. This annoyed her as her face began to distort.

With a burst of noise, Amplifier lunged at Trash-Chan at high speed. It was too fast for Trash-Chan, and she was smashed into the wall of the school.

"Hey, you ripped my maid costume!"

"You have more important things to worry about right now." Amplifier said as she held Trash-Chan up to the school's wall.

"Trash-Sensei!" Tanaka-San yelled. He ran over and delivered a kick to Amplifier on her wrist. She let go of Trash-Chan and backed away while gently rubbing her wrist. Tanaka-San held his fists ready.

Then Amplifier charged at Tanaka-San. She centered a punch into his stomach. He took the blow and slid back unfazed. He spun around and threw out a back kick at Amplifier. Then he tried using the momentum to spin back around in a roundhouse kick. Amplifier was hit by the back kick but caught the roundhouse kick before it made contact with her head. She smiled and grabbed onto his leg with both of her hands.

With a simple motion, she twisted his leg. The force of it was enough to twist his body with him, and Tanaka-San lost his footing. He fell face down on the ground as Amplifier let go of his leg. She stepped on his back to push him to the ground before he could get up.

"Otaku-Kun!" Trash-Chan yelled. She summoned her whip and snapped it at Amplifier. It wrapped around Amplifier's waist several times before Trash-Chan tugged it. Amplifier was pulled off Tanaka-San and thrown into the school's wall. Her back collided with the building.

Amplifier, unfazed by crashing into the building, sighed in disappointment. Tanaka-San described it as the kind of sigh a parent makes when they see how much their child has spent on anime merchandise. I think he let his personal experiences factor into his descriptions.

"I thought you would put up a little better of a fight. After all, you are Tai-Kun's waifu," she commented.

"You know Juyo-San?" Tanaka-San asked while pushing himself up with shaky arms."

"Why yes, I was his family's waifu many years ago. You could say we are as close as family."

"So, you're the witch that abandoned Main-Kun! He's had a rough life because of you." Trash-Chan said with an unfriendly smile. Amplifier didn't like that. In a flash, she was in front of Trash-Chan. She delivered a punch to Trash-Chan's stomach. Then she gave an uppercut to the chin. Amplifier locked her hands together and smashed both back down on Trash-Chan's head.

Trash-Chan just smiled smugly.

"Was that supposed to hurt?" Amplifier stepped back and ran both her hands through her lengthy, black hair. She took a deep breath before responding.

"I guess you will be a little of a challenge."

"What do you even want with Main-Kun?"

"I am here to take care of you. You see, my lady had decided that you are an obstacle that needs to be eliminated."

Tanaka-San grabbed on to Amplifier from behind. He threw her over his shoulder, but she gracefully did a flip in the air and landed on her feet.

"Trash-Sensei. She is an expert in hand to hand combat, but she can only use sound-based attacks at midrange. She will have to be careful here since her attacks make a lot of noise. We should be able to stop her in a fight here!" Tanaka-San yelled to Trash-Chan.

"Otaku-Kun, you probably shouldn't be fighting. Your more beat up than either of us."

"Don't worry, Trash-Sensei, I know my limits. I won't fight in a battle I'll get killed in!" Tanaka-San declared. He never did tell me what additional training he underwent to get this confidence.

Amplifier made a devious smile.

"I guess I should expect an otaku to know all about me. It takes the fun out of finding out about your opponent, though."

"Hah, well, sorry to say, but I've watched every episode of your anime. With my knowledge and Trash-Sensei's skill, you can't defeat us." Tanaka-San declared.

"Very cute." Amplifier said. In an instant, she was in front of Tanaka-San. She punched him in the stomach. He slid back about a meter and then dropped down to his knees.

"Her speed can rival sounds." Tanaka-San managed to spit out. Amplifier cracked her knuckles then appeared to materialize in front of Trash-Chan. Amplifier threw a punch at Trash-Chan, who dodged the blow by tilting her head slightly to the side. Amplifiers fist only flew past without making any contact.

"Hmm, so you're a little fast too?" Amplifier mused. They remained standing in the same position as they talked with Amplifiers fist still hanging out in the air and Trash-Chan's head tiled to avoid it.

"You're pretty fast yourself, but I imagine you can't go at full speed here."

"I suppose your right, and if I went full speed, I would cause a sonic boom. Can't be getting in trouble for that today."

The two waifu's smiled at each other before breaking out into combat at an incredible speed. Trash-Chan matched Amplifiers speed while trading a series of blows. Tanaka-San described it to me as watching a recording from a fighting game, like Mortal Fighter, between two pros. Except it was sped up to 3x or even 4x the speed of normal.

The two waifu's apparently exchanged a series of blows and special moves on a 2D plane at this rapid speed for a matter of minutes if Tanaka-San's description is to be trusted. As far as Tanaka-San could tell, they were each getting blows in on each other, but neither was decisive enough to finish the job.

Tanaka-San pushed himself off the ground. He charged into the speeding fight and slid into Amplifier's legs like a baseball slide. She was not prepared and was knocked off balance. Trash-Chan gave her a flying kick to the chest, which knocked her to the ground. She landed in a seating position.

Trash-Chan stretched out a hand to Tanaka-San and pulled him off the ground.

"I should yell at you for getting involved, Otaku-Kun, but that was a good assist," she said while patting him on the back.

Amplifier stood up from the ground and ran her hands through her hair. She rolled her shoulders then smiled at the two of them.

"Well, I thought I could just have some fun, but I guess I have to get serious."

Before either could react, Amplifier was in front of them. She gave Trash-Chan a screeching punch that threw her several meters back. Trash-Chan landed on her back; she looked up to see Amplifier cup her hands around one of Tanaka-San's ears. Tanaka-San seemed to shudder and stumble away. He pressed his hands over his ear.

"You... didn't do that in the anime..." he said before falling face down on the ground. He didn't bother putting his hand out to stop his fall and only hit the ground face first.

"You should have read the manga," Amplifier mused before looking over at Trash-Chan to smile.

"What did you do to Otaku-Kun!" Trash-Chan yelled as she stood up.

"Simple, I delivered a sound attack while dampening the sound with my hands. I call it the whisper of sweet nothings."

"Otaku-Kun, are you okay?" Trash-Chan yelled. Tanaka-San didn't answer.

"There's no point in talking to him. He is in too much pain to notice anything else right now."

"You..."

"Don't worry. I only made it a light level of sound. It should have only been about 150 decibels. About the equivalent of having a gun go off next to his ear."

Trash-Chan charged at Amplifier. She wrapped the Trash Whip around Amplifiers waste and threw her into the air. The whip snapped as Amplifier left the ground. Then Trash-Chan jumped up in the air and landed a kick that pushed Amplifier even higher in the air. Trash-Chan pulled another whip and threw it up to wrap around Amplifier. She tugged down and smashed Amplifier into the ground.

"Not bad." Amplifier snidely said as she laid on the ground, staring up at the sky. She threw her arms forward and stood up in a single motion. "But you will have to do better than that to defeat me." She brushed the dirt from the ground off her.

"Don't count me out..." Tanaka-San stood up with only one hand covering his ear. He slowly lowered it and shook his head. Amplifier smiled and walked over. She gently pushed Tanaka-San with her index finger, and he fell back over. "Actually, Trash-Sensei, I think I might be out of this fight now..." Tanaka-San said as he collided with the ground.

"Pathetic," Amplifier said while looking down at Tanaka-San.

Trash-Chan lunged forward at Amplifier. Amplifier smirked and, in an instance, was standing behind Trash-Chan. She tried to cup her hands around Trash-Chan's ear, but Trash-Chan ducked away.

"Don't go thinking I'll let you get close enough to use that."

"Hmm, I suppose you wouldn't."

"Hey! What's going on here!" A voice yelled out. They all turned to look at someone on the other side of the rope. Trash-Chan did not recognize the man, but Tanaka-San did.

"The... school principal..." he muttered why weakly looking up from the ground.

"I guess we will have to postpone this fight for later, my dear Trash-Chan." Amplifier flipped her hair and strode past Trash-Chan, Tanaka-San, and the principal.

"Oh! We need to get these groceries to Main-Kun!" Trash-Chan yelled. She ran over and began to frantically pick up the bags of groceries I had asked for. Tanaka-San pushed himself off the ground and grabbed the rest. They ran the rest of the way to the classroom.
