Drain Dungeon v.1.03 / ドレインダンジョン ～サキュバス風俗のある遺跡～

"When you leave this place you will return to Level 1.
Since that's the case either way, won't you let us feed on your experience?"

In a strange labyrinth that resets a heroes's level upon exit,
you are offered a deal by a pretty life-draining vixen
.
In order to defeat a certain someone... They need to grow strong.
and they need YOU to grow strong... so they can slurp your levels away.

A prospect of pleasure... your answer is simple.
