Grats on the pull, man. That's a nice new gal you got in the Chainsaw Babe.
Edit: Seems like there's a bug in the current event. If you don't kill all the mobile pests but still kill all the bosses you still get the 3 Star Rewards for killing all the pests anyway.
Dunno if this is intended or not since some maps have only bosses and mobile pests.
