Nice chapter. I wish The mask didn't have horns, it just doesn't seem needed. Don't think its ichigo in control because the hollow side told him, that if he slip up, it will take control of him.
For ppl who are not happy with the random power up, all I say to you is it could be worse. Look at naruto the main character, 400 and some chapter in and he is still weak. Personally I rather have the main character kick ass with random power-up then watch side character take the glory all the time.
