Gotta agree with Eligos and Nike despite me preferring long-haired girls. With Eligos... well maybe we can argue all day for her being blunt towards people... while with Nike, man, I would just sleep for eternity with her since she's a nice companion not to wake me up anytime, but err, not while working.
I'd like Ryu-Oh to hug me while getting suffocated with her well developed personalities. I'd die happy!
