Afer watching Negative happy chain edge, I'm always wonder about his blond hair in this movie. I'm 100% sure that his blond hair in koizora is wig. but in this movie, seeing his blond hair made me feel that his blond hair was his real hair with blond perm. do u have any ideas about this?

I've never read anything about his hair in Koizora being a wig. Actually I've read somewhere that after filming Koizora, they used the fact that he was blonde to include him in Negative Happy Chainsaw Edge.

Also, here's a pic from his blog, I think this proves that it has always been his real hair :)

really? actually i always love his blonde whether or not it is his real hair or wig. just make a post to make sure everything. thanks 4 ur reply.
