Chapter 15
Deep in the forest on the outskirts of Valentine Garden. At its center stood the colossal World Tree, Yggdrasil, as if holding up the sky. Its trunk was so thick that dozens of people joining hands could barely encircle it, and from each branch, a profusion of silver leaves emitted a gentle flow of magic power. Called the source of life, the World Tree was the heart that circulated magic power throughout all of Valentine Garden. And beneath it, the Black Knight was silently gazing up at the World Tree.
".........."
He was slowly scanning the trunk from behind his black helmet.
Thud.
At that moment, a voice came from behind him.
"Umm... excuse me...."
When the Black Knight turned his head, a woman with orange curly hair wearing a light green robe was standing there with a very nervous expression. She was clutching a thick notebook tightly to her chest, unable to meet his gaze properly.
"I, I am... a professor of Magical Ecology at Valentine Garden... in charge of managing Yggdrasil... My name is Eileen...."
She bowed deeply, hesitated for a long while, then carefully opened her mouth.
"By any chance... are you interested in Yggdrasil...?"
"......... It seems useful."
A blunt, ambiguous answer. But at that one word, Eileen's eyes sparkled slightly.
"Th... that's right... I don't know what use it is, but I'm glad...."
Smiling shyly, she carefully opened her notebook.
"Yggdrasil is... really... an amazing child... Even now, it keeps producing the magic power needed for Valentine Garden... The leaves change color slightly with each season... The roots hold the entire floating island together..."
At first her voice was small.
But once she started talking about the World Tree, her words gradually grew longer.
"Ah, and... by looking at the tree rings on the trunk, you can tell the magic power concentration of that era... In spring, new leaves grow about 18% more than usual... I check its health every morning at six o'clock... Yesterday, a new shoot came out at the tip of the seventh branch on the left... It was really cute...."
"...........?"
"And also... Yggdrasil really loves rain... On rainy days, the scent from its leaves changes a little... I collect that scent and record it... Ah, would you like to see it? I have an observation log compiled over the past 12 years... Seasonal growth rates and changes in leaf size, everything...."
The Black Knight looked at her without a word.
"Ah, it's not over yet...."
Eileen, having forgotten her nervousness, continued speaking while flipping through the notebook.
"This is the growth record of the branches... This is the magic power circulation of the roots... Ah, and my favorite part is its characteristic of recognizing certain actions and responding appropriately next time...."
"........"
After a moment of silence, the Black Knight slowly approached her.
Clank. Clank.
"Ah... huh?"
Eileen, absorbed in the World Tree, finally looked up.
"Umm... excuse me... I'm sorry if I was too annoying...."
Fearing she might have upset the Black Knight, she immediately apologized.
"Hey. Does that tree have any holes?"
"H... holes?"
"An old tree like this should have a few holes, right?"
"You're... asking about that?"
Her shy, cautious demeanor from moments ago was completely gone. Clutching the documents in her arms, she took a step forward.
"As expected, you are interested! Most people just look at its size and pass by... It's really rare to meet someone interested in the internal structure of the World Tree."
Clearing her throat once, she tried to hide her excitement as she continued her explanation.
"In the trunk of the World Tree, there are naturally formed cavities, empty spaces. But they are completely different from the holes caused by rot in ordinary trees. Those spaces are like organs the World Tree creates to circulate magic power on its own..."
"So where is it?"
The Black Knight cut off Eileen's words and asked directly what he wanted to know.
"It's... in the trunk part..."
The professor pointed at the World Tree with her fingertip.
"Hoooh."
Clank. Clank. Clank. Clank.
The Black Knight left Eileen behind and walked toward Yggdrasil.
"Wha... what are you doing--?!"
Eileen cried out at his sudden, unexpected action.
"This thing, you said it has a learning function, right?"
At the Black Knight's question, Eileen's face flushed.
"You... you were listening to everything I said!? Yes!! That's right--!!"
"I see."
Thud.
As the Black Knight positioned himself against the massive trunk, Eileen looked puzzled.
"But what exactly are you going to..."
"I'll teach you how to jerk off."
"Eh...?"
DRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR--!!!
The Black Knight grabbed the massive trunk and began thrusting his lower body into the hole of Yggdrasil.
"Grrroooohhh yeah--!! I love the texture of wood--!!!"
"Eeeeeeeeeeeeeeeh--!!!!"
"Th... this feeling...!! This must be what the World Tree edition torso that I had to throw away when my little sister caught me felt like--!! Grrrroooohhh yeah--!!!"
The Black Knight spouted completely incomprehensible information while continuing his intense jerking off. As a side note, for those who don't know what a torso is, think of it as a sex toy made in the shape of a torso.
DRRRRRRRRRRRRRRRRRRRRR--!!!
Meanwhile, at that time.
Central part of Valentine Garden.
"That's strange. Don't you feel the ground shaking?"
"It's probably just your imagination~!"
The students sensed something unusual, but brushed it off as nothing.
"More importantly, she said she's returning today--!!"
"I wonder if she received the title of 【Disaster Slayer】 this time?"
Not just those two students, but most of the magicians in this garden were anticipating. The strongest magician of 【Valentine Garden】, returning after a long mission.
"Bella. I think you should meet her too."
This was the practical training ground. Subaru suggested to Bella, who was sitting on the floor resting.
"Huff... huff... That powerful magician you mentioned?"
"Bella. That magician is one of the top S-Rank magicians. She is someone who can help us reclaim 【Maginova】."
At Siv's explanation, Bella was impressed.
"Oooh... I'm curious what she looks like?"
"She might have arrived at the headmaster's office by now."

Back again, this was the forest on the outskirts of the garden.
Eileen was on her knees on the ground, staring blankly ahead with dead eyes.
"It's... it's all your fault...!! How dare a tree have such a sexy body--!!! Grraaahhh--!!!"
DRRRRRRRRRRRRRRRRRRRRRK--!!!
She, at the Black Knight's piston action so fast that a woodpecker couldn't compare...
"I'm sorry... I'm sorry, Ygg...!!"
Drop... drop...
She was shedding tears of despair.
Rustle.
"What the..."
In the midst of the Black Knight's World Tree fucking, someone's quiet voice came from beside them.
"Eh...? Miss Touka...?"
Eileen was surprised to see the girl who appeared beside her.
The girl had long, light pink twin tails tied with black ribbons that reached down to her waist. Also, her black gothic dress, contrasting with her pale white skin, was decorated with frills and ribbons, and a purple gem was attached to the collar, giving off a calm yet gloomy atmosphere. What caught the eye most were her fluorescently vivid pink eyes. But those eyes were filled with fear rather than beauty. Her pupils were shaking widely, and the corners of her eyes were red and wet as if tears were about to spill.
"What the hell is that guy...!!!"
The girl called Touka pointed at the Black Knight, who was vigorously shaking his hips against the World Tree.
"I... I don't know him either...!!! He suddenly asked for a hole...!!!"
"I'll kill him...!!"
"From now on, you're my personal wood hole...!!! In my entire life, I've never felt such an amazing hole--!!!"
"I'll kill youuuuuuuuuuuuuuuuuuuuuuuuu--!!!"
"What kind of bastard yells while enjoying a wank...!!!"
Swish.
As the Black Knight turned his head with an annoyed voice...
"Oh shit."
___. ___
Back when the Black Knight was a delinquent.
There were three times he truly experienced pain.
The first was when ■■'s ■■ was destroyed.
A pain he could never forget, and a pain he tried to forget.
The second was when the mother who took him in was killed by a Disaster...
Due to his constitution that attracted Disasters, the day he alone survived remained a wound for the delinquent.
The third and last time was...
"If you die a dog's death, then Mom will die a mother dog's death."
"Take it back...!!"
In a small room lit by the sunset. A young delinquent was arguing with a girl standing before him.
"No. I'm saying this as your older brother."
"Take it backkkkkkk--!!!"
Smack--!!!
"Kyaaaaahhh--!!!"
The delinquent's arm was hit by the girl's fist, and he writhed in pain.
Thud...!!!
As the delinquent fell to the floor, the girl, as if waiting, mercilessly beat him.
"Take it back--!! Take it back--!! Take it back--!!"
Thwack--!! Thwack--!! Thwack--!! Thwack--!!
"Sp... spare me.."
Thwack--!!
"I'm sorry--!! I take it back--!!"
Thwack--!! Thwack--!! Thwack--!!
"I said I take it back, you bitch, stop hitting me--!!"
When he was beaten half to death by his one-year-younger little sister, suffering injuries that took five weeks to heal. That was the most physically painful time.
And... returning to the present...
("Mother... fucker...")
The Black Knight, who had been wanking on the World Tree, was about to have the worst reunion with his little sister.
"I don't know who you are, but when someone is enjoying a wank, you knock before entering. Didn't your parents teach you that?"
Huh... It doesn't seem like the worst for the Black Knight.
"Come out--!! Pen--!!!! I'll tear that pervert apart--!!"
But for the girl, it seemed to be the worst.
