"20,000 years of punishment? I’m sure that is more of a great reward, to you. Rather, I think the only one being punished here is Valkyrie… Spending twenty thousand years thinking she’s punishing someone, when in fact he’s enjoying it. Valkyrie is a battle type angel. She uses powerful spear skills. Although she has high defense, like any warrior she is weak to pleasure attacks. She should be surprisingly easy to beat if you use pleasure attacks. Now go, oh Brave Luka. You should rape Valkyrie and punish her for the next 20,000 years now. ...Forgive me. That's a rather long time to gloat just for getting revenge."
