can anyone tell me when is ruka's first appearance? i'm starting to forget....

you shouldn't be the only one forgetting about him :P maya should do the same, i am sure nemu would feel quite happy with it. like: 'ruka, should we have met yesterday? sorry, i was fucking my boyfriend all night.' nice cold water on ruka manipulativeness.


ps: i don't remember either when he appeared. lol

I think Vol.6
