Rini blinked her eyes. Why did Onii-san and Onee-sans entangle their naked bodies even though they were this sweaty? Was this some sort of new training? The sudden tingles in her body weirded her out even more. Rini couldn't wrap her head around anything.

"Rini, did you break the doorknob?" Asahi asked, still hugging Leme. ​​

Rini tilted her head. "I opened the door normally."

"Impossible. It was properly locked," Saya said. "Rini is losing control of her strength."

Rini looked at her hands. "Am I losing control...?"

"Rini… Rini."

Rini ignored Asahi's calls as her eyes were glued to Asahi's body. Her fingers trembled, longing to touch those muscles.

"Rini!"

A shout finally yanked her back to reality. Asahi turned to his side and shielded his body with Leme.

"I'll meet you later, okay?"

Rini nodded and sprinted out of the room, only stopping inside her room.

I ignored Onii-san. Will he be angry at me?

She sunk into the couch. The scene replayed in her mind, again and again. Her eyes became dreamy, and her heart accelerated. A familiar urge engulfed her. Her hand crawled down to untie her skirt.

"Rini Nee-chan!"

Rini pulled her hand and took a deep breath. Aiko skipped into the room and hopped on the couch. With her legs dangling childishly, Aiko nudged Rini.

"Nee-chan is forgetting her favorite anime."

"Blooming Sunshine is airing?" Rini glanced at the clock. "I missed half…"

The only anime she watched. It was the story of a taciturn girl adjusting to her life in a new city and a new school with the help of her brother. Something about the show made it endearing.

"Don't worry. Aiko asked Shizuka Nee-chan to record the show."

Rini smiled at Aiko's smug smile. Reaching out, she patted the little girl's head.

"Thank you."

"No problem!"

[Asahi POV]

I pulled out of Leme and closed the door with the telekinesis. I might need to barricade doors to stop this trope.

"That was, uh, super awkward," Leme said and got up from Saya's lap. "Rini-chan's affection level is going up. Master, Rini is yearning to become your woman."

"Nope." Saya shook her head. "It's her instincts."

Why now? I remembered Rini's eyes before she left. It resembled Rika's predatory gaze when she wanted some love. Was Rini finally losing to her monster instincts? I and Nee-san needed to have a long chat with her. A woman was necessary to stop Rini from jumping on me. If alone, I'd most likely let loose my desires and claim her.

"Forget her for now. I want more love~."

Saya tackled me. I flipped our positions, pinning her down.

"Where is my cute Saya?"

"Am I not cute?"

"Of course not. I just wanted to make love to her."

"She is feeling everything from a backseat, awfully bashful. Let me drag her out here..."

Saya closed her eyes for a few moments. When she opened them again, she was back to her normal eyes.

"W-Why did you call me? I was having some rest there."

"I wanted you," I leaned down and whispered in her ears.

She tried to put on a strong front, trying to weasel her way out. But Leme and I coaxed Saya into a long loving session.

[Danmachi world]

I teleported into the dungeon, where the girls already awaited me on the cliff of the Great Fall. Saeko's grin pretty much told everything about the upcoming event.

Rika raised her head from her phone with a toothy grin. "Just in time, love."

"The party is starting soon," Shiori said.

Tremors took over the entire floor. Fissures formed upon the walls. A monstrous howl stemmed from the dungeon itself, and the Great Fall exploded. I flew, stopping a bit short from the ceiling, and cast my gaze down. Another water explosion and a massive creature wrapped in white mist burst out of the waterfall. It plummeted into the bottom pool before surfacing to show its two white dragon heads; the right one had red eyes while the left one had blue eyes.

I grabbed my good old appraisal glasses.

[—Water Element Resistance (F): The monster gains Water Element resistance in its natural habitat.]

Oh man. Amphisbaena boasted quite the mana in its colossal body. Even its stats were a cut above Ais, a prodigy in her own class.

The monster suddenly went inside the water and launched itself in the air. Its claws dug into the mountain as it began to climb up.

This thing was huge, over twice the height of a truck, yet it still nimbly swam in the water like a serpent. It stopped right under the waterfall and let out a terrifying roar.

The water erupted up and smashed through the fragile cliff. The raging wave became a tsunami. The girls remained motionless as the tsunami split and flowed to the girls' side as if it was afraid of drenching them. Was it Saeko's water element, Rika's telekinesis, or Nao and Shiori's wind element? Maybe it was the combination of all those abilities. I couldn't help but be astonished at their growth. They used to be normal humans not long ago.

The beautiful dragon that could make any average adventurer piss their pants in terror; it looked up from the pool. The two heads, which were split from the base of its neck like a hydra, gave a menacing glare at me. The girls looked down on it with slight mockery.

My fiery wings blasted, taking me to my right place—in the middle of the excited Busujima Twins.
