Warning: Possible Kotoura-San Spoiler....

...

Just learned about Aki Tsukino's alter ego today in the pen-ultimate episode of Kotoura-San. I so didn't want her to be the culprit, she was a nice police lady.

Yukiko from 11eyes

Yugi and Atem/Yami Yugi, Bakura/Yami Bakura and Marik/Yami Mark. The first two share the puzzle and have a strong bond since they seem to trust each other and depend on the other for things, though Yugi can't handle dealing with bullies like Kaiba let alone a bunch of freaks that could wipe him off the face of the planet, and probably Atem wanted a purpose. They probably didn't expect to become friends or duel partners. They care about each other, though it's shown differently from them. Yugi would probably be nervous for Atem and not want him to risk his life for him, though, then again, the feeling would be mutual. Atem wouldn't want Yugi to do that. But if Yugi was in danger, meaning that someone was TRYING to kill him.......oh, man. Atem would be PISSED. He'd probably come out and challenge the attacker to a Shadow Game, and the attacker would be on the receiving end of a Penalty Game, meaning that the creep would probably get killed.
