So, I suppose Erika needs her "opponent," she does get easily bored. ^^
Oh, and another note, I feel like I'm really the only Umineko fan here. Especially when the series is a complete mindfuck once you manage to finish all of the eight visual novels on it. XD
Name: Battler Ushiromiya
Nickname: N/A
Age: 18
Gender: Male
Abilities: (Note: His abilities are based on how they are at the end of the series)
Battler has both the ability to access the Red Truth, the Blue Truth, and the Golden Truth once he is pronounced the "Endless Sorcerer" to orchestrate the 6th game. His knowledge is quite at par against Erika's, though, he doesn't put much mind into the Golden Rules of the mystery genre, which Erika uses to her advantage. His only trait that would counter that is his ability to "create" anti-magic toxins, which he still possesses strangely after becoming the Endless Sorcerer. Due to his persistence to reject the existence of magic long before becoming a sorcerer, it gave him access to use those anti-magic toxins in the level of "Endless Nine," which is the most dangerous level to deny the existence of magic and witches.
Species: Human / Sorcerer
Appearance:
From: Umineko no Naku Koro ni
Other: An example of Battler's logic (5:14 to 9:53, 36:14 to 38:15)
