With dick powers like that this manga could easily transform into battle series, btw I have a feeling that girl with flower in her hair is low-key main heroine with amount of scenes showed from her perspective.
It's kinda getting ridiculous, soon in will be: "Oh no, it's a chair that Takagi just sat in! If I sit here it's like I'm touching her butt! That's too embarasing! I can't sit here now!"
