Don't watch this. I will say right up front, before I say anything else, don't watch this, even if you are curious about how bad this is, don't do it. You won't have fun, this anime isn't so bad it's good like other people might have you believe, it's just bad, it has no redeeming qualities what so ever, well maybe the first 15min of the second episode is funny, but that's about it. This is utter trash.
The premise it's self isn't really horrible, yakuza boss's daughter picks a teacher to protect her, really if this was handled a lot better this could have made a good anime. But no what we get here is something where it feels like a hentai anime that they took the sex scenes out of at the last moment. The art is so so, it's tolerable even though our 20 something high school teacher protagonist looks like a very tall 12 year old for some reason. The animation though is awful and approaches Twinkle Nora Rock Me tier at many points, there is a point in the first episode that is animated so lazily that it looks like a group of students are floating past a window. The personalities of our main charters seem to change at whim, at the beginning of the first episode the yakuza daughter is a floozy that will do anything to get what she wants, and seemingly she wants to jump the teacher. But that is all suddenly forgotten about half way through the first episode where she is suddenly a complete innocent that needs saving and doesn't know BDSM from a school dance. And then we have the second episode, which actually starts out very funny but quickly goes down hill. The episode culminates in a low ranking Yakuza who's personality "changed" after he stabbed some one kidnapping our main girl in order to rape he, which it seems everyone wants to do in this anime actually, but I guess it's super bad and not just "hahaha, it's so funny they want to rape her" this time because he's mean and violent. Anyhow it turns out that he is just mean and violent because his friends turned his back on him because he stabbed some one in cold blood... and I guess we are supposed to feel bad for him?... really?... REALLY?? And this is all revealed in a confusing scene where our teacher hero, barges in drunk, acts like a coward multiple times, and... yeah... really I don't feel like going on about this anime any longer. This anime is dreadful, it's not worth anyone's time, don't watch it, the end.
