If you could pick then who would have or believe would be a cool guest character for a Megaten game? Even if you do not like the idea of a guest feel free to say why.
If it was in my hands to pick a guest then I'd probably go with someone from a manga instead. Kinda like Kyosuke Date from Soul Taker. He seems to have that creepy as all hell aura about him especially when he tells Shiro about why he should not want the dead to be resurrected. But that's just an idea cool one IMO but idea none the less. Any thoughts?
