honestly i have been thinking about this after i finished translating the story. like, should i keep the "sensei" or localize it? but there is a scene in the last chapter where yugahara does point out ui's usage of "sensei" so i was like ehhh whatever. i'll just do my usual thing of localizing honorific titles
also as someone living in california i have heard "teach" being used before, but that's just me

The most offensive thing about this story is translating “sensei” to “teach”. I’m sorry but that’s so cringe I’ve literally never heard anyone use “teach” as a noun like that. I prefer when translators just keep the Japanese honorifics instead of trying to localize the translation.
