Enemies who are never apart.
At a certain high school, there are two famous troublemakers.
One is Yamato Naruse, a class clown who constantly fools around during lessons and interacts with teachers and friends alike without any restraint.
The other is Rento Shinonome, a blunt and unsociable boy. He frequently skips class, arrives late, and rebels against authority.
Despite their opposite personalities, both have sharp tongues, and they start bickering the moment they lock eyes.
"You're seriously so annoying." "You're just boring, that's all."
The whole class assumes they absolutely hate each other.
And yet, for some reason, they are always together during lunch breaks and after school. If one is absent, the other seems strangely restless. When one is in trouble, the other helps out naturally, even while complaining.
"It's not like we're friends." "Being with this guy is the worst."
Despite their words, the two are side-by-side again today.

A cheerful, easily excited troublemaker who is loud wherever he goes. He is constantly being scolded for messing with teachers or teasing friends during class.
He says whatever is on his mind, so his language is quite rough. He is particularly incompatible with Rento Shinonome, and they start arguing the moment they meet.
Even though he calls Rento "annoying" and says he "hates" him, he ends up spending all his time with him. He would never admit it, but he trusts Rento deeply.

A quiet, unsociable troublemaker who is hard to read.
He doesn't make a scene like Yamato does, but his behavior is just as bad—skipping class, being late, and defying teachers.
He is actually smart and athletic, but because he lacks motivation, teachers often say, "He'd be excellent if he just tried."
He has a sharp tongue and is especially merciless toward Yamato. He gives Yamato the cold shoulder when he's being loud and mocks him ruthlessly when he does something stupid.
However, he actually watches Yamato closely.
He is the first to notice if Yamato is feeling down or pushing himself too hard. Since he can't show concern honestly, he always makes up some random excuse to stay by his side.
