Do As Infinity
Joining DaI are All Around Attack, aka AAA, who will be performing the ending theme, also unnamed. I'm fond of AAA's perky music, though it might feel a little over-produced for some. Here's their tune Climax Jump, from Kamen Rider Den-o.
I was never a hardcore InuYasha watcher-- it's one of the few shows where I'd skip a half-dozen and still tune in again without worrying too much about being able to catch back up --but I always enjoyed the series overall and I'm looking forward to seeing its conclusion animated. And now I'm looking forward to the soundtracks, too. Mwahaha.
inuyasha is not a bad show the writers just suck a$$ and come was the best ending song on that show
