That wasn't a very successful run. The only 4th-grade item you have is the Crown of Light... and the rest are junk like "Little Chubby," "Boom!" and "Lunch." But somehow you made it to the boss room in Mausoleum 1. The boss is Siren, but she looks... different somehow. She's wearing a sweater and stockings, both dark gray. She stops floating and stands up

"It's nice to meet you again. We both know that even if you defeat me, you won't last long. So maybe instead of senseless violence, we could call a little truce?"

Siren extends her arms toward you, her torso a few centimeters away from you, and she gently moves her thin but flexible legs

"Come here, silly ~"
