That's the thing, Tenryū looks like a delinquent, and then you catch her outside of the school looking after her kid sister and the whole "bad girl" mystique shatters into a million pieces.

Meanwhile, Tatsuta is the kinda girl that guys just instinctively avoid, as if she has "psycho" written all over her. Sure, she doesn't look particularly scary, but she has that twinkle in her eye that says "They'll never find the body." But, she's also depicted as a massive troll, so it could just be that she's capitalizing on the unease she inspires in others for her own amusement.
