Hope it's not out of place for me to correct you on name pronounciations!

鋼兵 (Kouhei)
ヲタ姐(Wotane, or Otane as she romanises it)
終太 (Owata)


Also have to agree with you - IMO lately most of Valshe's covers seem lacking...D:. And not because I'm bored of her voice or anything - my old favourites from her are still favourites. But something's missing from her singing these days...and I think it's emotion?
