Nago-kun, sad.

I'm "gin gin" too.
No more violin?

Jirou wants Yuri so he can revive his race?
Wouldn't that be half-Wolfen?

Will Kengo get gin gin with Wataru's violin play?
Yup, it did.
Wataru made a good friend.
Will Kengo become a tool against Wataru?

I don't really get how Nago became like this.
What I remember vaguely: he wrote his father's wrongdoings in his report and got his father killed.

Its a love triangle in the past.
Nago's obsession to defeat Kiva in the present.

Life is pretty boring in Castle Dran.

So the IXA belt appears to whoever holds the fist?
Otoya is pretty good.
