>This new character came out of nowhere
not true, she was foreshadowed with the cultural festival idol performance on how Honoka looks like her, it was just a matter of time when she'll actually show up.

>starts teasing the main character for no reason
it was a chance encounter at first, but it turns out her family owns the building the MC and she live in, which is probably even stupider than her becoming a teacher, more than teasing him, she was drunk iirc, which also makes it stupid

>and the girls are jealous of her despite the fact that she's a teacher
Himari is jealous because she is a bigger deal than her, Honoka is jealous, because she already was jealous when she was singing her part during the idol thing, Kanna is also jealous because her showing up is a bigger deal, her being a teacher is irrelevant since she is a former idol.

>that's not the tone of this series
nah, Kanna's inclusion already showed what the tone of the series is
