Madow had asked around as to the whereabouts of the remains of the water beast he fought before, they ended up in the hands of some class-B student, so that's where he was heading. On the way he knocks over a cup of juice Luxanna was drinking with his quirk, just cause.
Getting there he sees that they're in the middle of class, so he goes to talk to the teacher while trying not to disturb anyone. "Hello, sir, I'd like to ask about the bones of the creature that was at the USJ"
The teacher smiles at him, a tall man with green skin and hair, having four tongues in his mouth. "Hey, Madow, right? You were great at the USJ. So, you're here for the whale thing?"
"Yes, that one" To which the teacher just points to the student with the bones.
The student had already finished the class assignment, having wrapped up the mock villain in a cage of bones. The student had skin as white as Madows, with hair of the same color, and a lazy look in his eyes.
"Good afternoon, I came to inquire about the bones from the USJ whale"
He yawns before looking at Madow, "Sup dude, who is you?"
"Madow, the guy that fought the whale"
"Oh the guy that got kidnapped, sure gave the teachs a lotta trouble, I got the bones preserved with my quirk" With a snap of his fingers the beast's skull appear out of nowhere, could be scary but Madow doesn't really care.
"The principal wanted to study what this thing even was, and how the villains made it. So they asked me to take care of the bones for them. Not that I mind, been a big help now that I can recreate them. I call them my gaster blasters."
"I'm going to need one of its spinal bones, a small one preferably"
"Just a piece? here." He gives Madow a vertebrae.
Madow proceeds to break it in half with ice and extract out the bone marrow from it, making it a kind of soup and drinking it. He then sits down, meditating to absorb the creature's powers.
After a while he gets up and shoots a pressurized beam of water, perfectly replicating the ones the beast used before, being much stronger than he used to do.
"I've finally broken through to the next realm of my cultivation, this will make my potential rise tenfold" It's not clear if Madow's quirk actually has anything of the sort of if he's just being an idiot.
They give each other a thumbs up before Madow leaves, after school, he catches a couple of fish in the sea, and after such a long month he deserves to treat himself, getting some spice for the fish and a cup of pudding "Really going all out this time"
'I really need some rest, the sports festival will be soon' He thinks while going into the darkness of his broken lighthouse.
