One day, there was a letter at your doorstep, but it wasn't addressed to you but to some guy named Lilia. For fun, you decided to write back to the sender, whose name wasn't written on the letter, and surprisingly, they wrote back. Now, who ever this person is, is your penpal, who you decided to call Tsunotaro.

You decided to meet up with this person, planning to meet him at an old park which no one visited anymore.

"Finally we meet, dear friend." Malleus said as he approached you.
