Poniko (EntityTopic, 7)
From Compile Worlds
Poniko is the cute little girl living in Madotsuki's dream world.
She usually ignores Madotsuki, and prefers to live alone (maybe because Madotsuki is batshit crazy a hikikomori). But, in the event that you do piss her off, she'll deprive the whole world of Sata andagi...
If you turn off the lights in her room, she'll reveal a secret as well.
