Tsugiri:

He is the main character of the manga, not well characterized in these firsts books, but this is quite obvious '^_^. He hates the Alichino because they seem somehow related with the death of his mother, even if it's not that clear why they're involved ... He's a quite one, brave but really cynical, probably his behaviour is due to his childhood, that's not well explained yet. It's clear, though, from the very beginning, that the author will explain better what happened back then (4 volumes aren't enough ;_;)

Personally: I like him, although I've always disliked the main characters... I don't know why, really, there are many other characters that fascinate me more *^_^*
