There is no rule breaking going on. You would know if you actually watched or read it.
Why is Kirito so intolerable and Maple so likable even though they're both overpowered?
Kirito was okay when he was a girl
imagine how much she farts IRL while she's playing like mmmm I wish I could smell
Kirito isn't overpowered, he's just always right
Maple
>lol what if I eat this demon lol
Kirito
>according to these spreadsheets if I distribute my points this way I have a 0.5% increased chance to save Asuna from the Rape Gangs
Thats the point, he is "One punch man" of course he wins every fight. But mary sues are perfect in every aspect. Their appearance is perfect, everyone loves them even their enemies. They never fail at anything.
>Killing bosses solo without any damaging abilitys
Evidently bite is damaging move
The comedy/pathos of OPM is that Saitama is berserkly powerful, but it's a hindrance.
The comedy of Bofuri is that Maple is berserkly powerful, but it's completely by accident. She's retarded and guileless, so her OP nature is retard moe.
The thing about Kirito is that his skills are not played for comedy or pathos. He's just good enough to obviate challenges that are presented as adding conflict to the story.
Saitama being OP causes problems. Maple being OP allows her to contribute to problems (and sometimes causes problems). Kirito being OP obviates problems.
>muh Maple is a sue
>was never the best in events
>had to drop out of certain events
>failed to kill certain bosses
