Miko

Miko is a yandere emo boy in the sequence world.

History
He dated Flippy and married him once. And that caused a never dying love. He now haunts and chases after Flippy nonstop, killing any foes in his path. When he loses Flippy, he enters depression mode until he can find Flippy again.

Location
MUAHAHAHA WHERE IS THE YANDERE BOY YOU MAY NEVER KNOW HE COULD BE RIGHT BEHIND YOU MUAHAHA---

Sorry about that. Anyways. Miko may be located in:

Tree Town
This is Flippy's hometown and likely location.

America
He thinks Flippy may be in the North American continent.

London Town
Well...

No
Miko has no idea Flippy is in London Town.

Immortality
His immortality is somewhat of a trident. He can stay alive as long as Flippy is alive, making him invulnerable to a 'permanent fate'. He can be killed when he loses love for Flippy, when Flippy is killed PERMANENTLY. Or if Ashley Veteran reverse seals him

Ashley's involvement in this matter
Ashley was the one who allowed Miko to be attached to Flippy's lifespan. And thus can end it as long as strengthen it. Ashley may be more of a trickster then Ashton.
