It seems to me that overall, things are more or less the same as they were last time. You seem present enough OOCly, you have great characterization and actively plot and don't seem uninvolved at all... Yet this doesn't reflect on your playing. Kamui seems very much away from everything, focusing only on threads with castmates like Fuuma or Kotori, or on threads with characters he can have shippy CR with (Subaru, Hokuto who can get involved with/tease about ships, and so on). They're the only people I've seen are able to hold your attention for longer than a handful of tags, and who get tags back regularly.
Selective tagging is something everyone does from time to time, and that's okay, but when it's this constant it starts to feel like there's no point in trying to get CR with your character at all, which sucks because he's really good and I'd love to see him build deeper relationships with more people.
