I think I might be the world's last Otoha fan lol. I don't like how long the plot stalled around her and Rin's relationship, but I still mostly like her as a character. Her chemistry with Akira above all is really enjoyable, like a mix of early Rin and Maya if that makes any sense, and at this point I'm a bit more interested with where the plot is heading with her than a lot of other characters currently, but that's probably because she recently got some new plot threads. I think she's up there with Uta on the "I wanna see where this is going" scale.
Also I was pretty into the cuck scene honestly. I like her design quite a bit, especially when she has her hair down, and have a weird thing for fully clothed masturbation. So that probably helped my impression a bit.
