Against people who are playing a skill based copy of SAO for only a short time versus a 2 year veteran with supposedly the best reaction time out of 10,000 players and all his skills practically maxed out, I don't think showing off was risky at all.

I just wish they don't do the disappearing slash thing. It is always lame, no matter how it is done.

Lyfa shouting Sei! on her first strike is a dead give away, even if they changed the voices.
