I wonder if this is an actual world building arc or if it's metafictional (e.g. one of Akigumo's doujins). The latter would be more in line with the rest of the series.

I wonder how this Ooi become this Ooi.

you perfectly dont need to befriend someone like her either Ooi. she's definitely a bitch

You don't need to be friends with shitty girls like that anyway, Ooi.
