There is the family grave. Several naughty members of your family (pre-war) are buried in the graves, but the majority of your (pre-war) family are buried in the colosseum.
You don't spend much time in there, but you have noticed your sister going in there on occasion. That's why she installed a lift from the house to the grave. You find it relatively fun, but you would only use it if you needed.
Satisfied with the anime reference, the possible frog teleportation, and more knowledge of your wacky family's history, you ready for your next task.
