Hate to break it to you, but Mana was always a dork, he just wears it more openly now
It definitely seems like Mana's doing a lot more of that fan appreciation kind of stuff lately though, and I know what you mean about being disappointed. Like, that sort of "breaking character" is probably fun for someone who's already seen them in-character a million times, but if you aren't part of the Japanese fanbase who's been going twice a year for the past decade, that's another story. This is yet another reason I hope Mana starts seriously trying to expand his fanbase again.
Thanks for the report
To some extent, but I feel like he's crossed a certain line now XD
I believe it happened more because it was birthday partying and anniversary reminiscing. From what he tweeted about the new song, he's still thinking about Moi dix Mois as dark, blackness vibe. I wouldn't give up on that yet.
