Elizabeth and Lenmia passed through thick vines and leaves and hills before they came to a strangely clean landscape, composed of soft, colourful grasses and lustrous herbs. They swayed with a gust of wind, radiating fresh fragrance and glittering pollens.

"Sister Lenmia, what is that?" Elizabeth stared at a mysterious tree in the middle of the grass plains, whose peak extended outwards, forming a dome which cast a soft, cooling shade across the grasses.

"Dear, it's a Soul Tree. You should've learnt about it in the human school." Lenmia guided Elizabeth under the shade towards the tree’s stem, from which a droplet-shaped fruit hung. Its golden, illuminating radiance invited a touch, but Elizabeth knew better than that.

She traced the vine-covered stem to its peak, where countless multi-coloured leaves fluttered and whispered into the forest their magical lullaby. The branches split into mazes, cracking open rifts on their barks for the scentful flowers to bloom.

"Wonderful, right?" Lenmia said. "It is hard to find a Soul Tree, let alone such a big and convenient one. This place even has a nice cave to shield us from the weather."

She pointed at a small hill a distance away from the Soul Tree. Despite its size, Elizabeth would have missed it under the plants and rocky ruins surrounding it. At the entrance, where light faintly penetrated the dark veil, three pairs of bright pupils quietly stared at Lenmia then shifted to Elizabeth, glowing with curiosity.

Elizabeth instinctively held her breath as anxiety bubbled in her body. Those pairs of eyes weren't of humans, but so wasn't hers. Her thought came to a halt when she recalled that she didn't need to breathe. She relaxed at once.

"Don't be nervous. They're just like you, wonderful and cute." Lenmia smiled at Elizabeth then waved her hand to those hiding inside the cave. "Sisters, you can come out! A new sister is here to join you!"

Before Elizabeth could adjust her manner, Lenmia abruptly dragged her to the cave. Though she didn't collapse into a pile of water, her body flushed pinkish while her expression struggled to maintain composure.

"Wait," Elizabeth cried. "I'm melting, Sister. I'm melting!"

"You're turning pink, Dear. You're turning pink."

"Please don't tease me."

By concentrating herself, Elizabeth collected her lost mass by moving them towards her. When she finally calmed herself down, she had already become the centre of attention of her unusual new friends.

"Sister Lenmia, what's her name?" a green-skinned Monster Girl said. She smiled at Elizabeth and tilted her head. The pink rose blossoming out of her head swayed with her movement and along with her long silk-like hair.

"I'm not the one you should ask, Dulcie." Lenmia sneaked behind. "Go on, tell them your lovely name."

Elizabeth took a deep, empty breath before she bloomed a smile across her translucent face.

"My name is Elizabeth Goodwill. I don't remember much about this world, so please take care of me, Sisters!"

"So that's your past name. Do you want me to help you select a new name?" Dulcie said and directed Elizabeth's attention toward the other Monster Girls. "Everyone here has chosen a new name for themselves, as we aren't our old selves anymore. It's better to leave the past behind and live the new life to the fullest."

Though the suggestion was lighthearted, the implication lingered in Elizabeth’s mind with such profundity she fell silent. Her watery body dimmed. She shifted her gaze from her friends to the cave where she would live to the fantastical wilderness to the horizon where many more magical beings dwelled then finally to her nonhuman appearance.

Her liquid body condensed under a layer of smooth membrane and regained its previous lustre, developing a firmer figure, which resembled her human self, filled with innocent beauty but also the mystical charm of a Monster Girl.

The shallow puddle which always existed under her unrefined body morphed into a pair of slimy, bouncy legs. The soggy texture of her surface merged into her membrane and tightened around her silhouette, gifting her tight curves. Hairs flowed groundwards and merged with her body like a waterfall.

"Elizabeth," Lenmia said as she reached out and touched Elizabeth, shaking her out of her sentiment. "You're simply amazing. I've never heard of anyone spontaneously undergoes a Metamorphosis before."

"Sister Lenmia, what is a Metamorphosis?" Elizabeth said then froze after hearing her own voice. Its sharp and pure quality resembled her human voice but saturated with subtle allure. "My voice came back?"

Elizabeth looked at herself and found a familiar pair of hands and bare breasts, which perplexed herself at first before the realisation hit her. She stooped down and concealed her exposed body with her arms.

She was naked! A maiden shouldn't be exposing her body to anyone else outside of her loved one. As an upright—human?

"Sister Elizabeth, are you alright?" a hoarse yet feminine voice rang. Elizabeth looked up and met a muddy hand. Its owner, a melting mud-like Monster Girl, forced a strangely cute smile despite her mud obstructing half of her face. "My name is Tardi. I'm a Mud Golem, please to meet you!"

Tardi was not too small yet not too tall. From her hair to her feet, layers of muds descended in multiple layers and coated her figure under a natural imitation of a maid uniform. Its brownness gave off a dull vibe, which contrasted the gleams in her silver pupils.

Elizabeth, still nervous, took Tardi's hand. The mushiness stuck to her skin, though she felt nothing but warmth in her heart. Despite her dirty appearance, Tardi was like a faithful maid who would stay beside her lord.

"I'm sorry, Sisters. I forgot I'm not a human anymore," Elizabeth said with great effort, and her friends chuckled.

"It's fine to be ashamed, Dear. Everyone's first time is like that," Lenmia said as she drew her hands around Elizabeth and pressed her body against the bouncy slime. Their colours merged as Lenmia caressed Elizabeth's body and stroked her breasts in a careful, calculated manner. "Be it you or other girls, I'll make you all a proud Monster Girl who could play everyone else under her fingertip."

Lenmia blew a puff of hot air at Elizabeth's face, whose colour shifted to red. She moaned and dissolved into a bubbly puddle of warm shame, filled with hints of confusing excitement. The promise hauntingly resounded throughout the surrounding, quietening with each repeating echoes.

Other Monster Girls revealed various degrees of embarrassment. Tardi looked at the ground while forcing her hands to stay still. Dulcie watched with a smile on her face and a finger on her lips.

"Dear, you can come back now. Staying like that won't erase your moaning," Lenmia said as she sniffed her fingers which had just played with Elizabeth. "It's lovely. You might even have a talent for this."

Elizabeth peeked out of her puddle body. Her mass converged into the same graceful body, though within it retained a hint of indulging heat. She was drunk-red.

"Please don't jump me like that, Sister. Even if we're both women, it isn't funny!" she said and gripped her body, forcing herself to stop trembling from the lingering sensation of touches. "Now, my body feels weird."

"You'll get used to it, Dear. I'm only doing this for your sake. If you don't prepare your body, how will you survive in this world?"

"Please don't joke with me." Elizabeth forced a dry laugh, but the atmosphere didn't lighten. Her eyes glanced at her friends. They agreed with Lenmia. "This is a necessity?"

Elizabeth lowered her head as her mind replayed the scene of confused sensations. Despite her conflicted mind, her body responded to it with suppressed excitement and vague anticipation. She was a Monster Girl, and it was normal for a Monster Girl to train her body.

She was falling with nothing to slow the descend. Even the reluctance in her mind gradually weakened. The alluring wonder of such a sinful, wicked act was too strong for a well-mannered maiden.

"Be at ease, Dear. I'll continue to feed you knowledge and practice until you can protect yourself," Lenmia said with an artificial quiver in her tone. The vibration sent a chill throughout Elizabeth's body.

"We'll help you too, Sister Elizabeth!" Tardi said. "I'm sure, with your sensual body, you will learn the technique in no time."

"Wait, wait," Elizabeth said and heaved an illusionary sigh. "Let's start with the basic first before we get into the advanced acts."

Before she could continue, Lenmia hugged her from behind, pressing her bouncy breasts forwards. She leant onto Elizabeth and caressed her cheeks with her face.

"Then, what is your new name? Elizabeth might be too long for your endearing personality."

Elizabeth paused for a long while, trying to come to term with the implication and the ambiguous decisions she had to make in the future.

"Iris. You can call me Iris," she finally said.

"Sister Iris, what does your name mean?" a new, muffled voice echoed. A Spider Lady came out of the shadow of the cave with a thick rock plate in her hand. Her upper greyish female body extended from her lower spider form, which composed of a carapaced abdomen and four pairs of pointy, slender spider legs.

Partially covered by her curvy dark purple hair, four mini black pupils existed in each of her two eye sockets. They spun in a circle whiling marvelling at Iris. Though her spider body looked huge, she was about the same height as Lenmia, not much taller than Iris.

As their gaze met, the Spider Girl quickly averted her eyes and turned her head away, causing her hair to fall and obstruct her face. Her bulky body only intensified the clumsy, careless vibe surrounding her.

"I'm sorry, Sister Iris. My name is Reta. I like reading and knitting clothes." Reta bent her spider legs and lowered her head until she almost touched the ground.

"Reta is like that when she is nervous. She'll stop being too formal when you spend some quality time with her," Lenmia said with a devilish smile. "She is very knowledgeable about certain things you might want to know."

Iris ignored her devil Sister and told Reta to relax.

"I would love to see what you've knitted, Sister Reta. Iris is a flower that symbolises rebirth and hope. It's perfect for this occasion, isn't it?"

"Sister Iris, are you saying that we are a family to you?" Reta said with a hint of excitement of a student who knew the answer to her teacher's question.

"That is what I hope. I'm the youngest sister, so please teach me a lot of things."

"We'll teach you, your body, and your mind, a lot of things," Lenmia said and let her voice trail off. Its lecherous tone lingered and seeped into every Monster Girl's soul. "There is one thing you're wrong, though."

"What is it, Sister Lenmia?" Iris said and turned to Lenmia, slowly retreating away to avoid another unexpected ambush. "Please, my heart can't take it if you're going to tease me again. It's still wrong, even if we're both girls."

"Then, why is your face inviting me with its adorable blushes?" Lenmia pointed at Iris's rosy face. "You aren't the youngest sister, Iris dear. You're the second eldest sister, after me."

"What?" Iris shifted her attention to everyone else. They merely nodded and smiled in unison at Iris's apparent status as the second sister. "Why me?"

"As I said, Iris dear, you are talented and charming enough. I'm sure you'll become the second sister they all will look up to."

Everyone’s eyes glittered as they stared at Iris, who felt an ominous chill. Would she also become naughty like her eldest sister? She hoped not.
