You Should Be Listening (Solution)

There are nine pictures, each containing six anime characters. In each picture, three characters share a Japanese voice actor and the other three share an English voice actor. There is a single notable anime character that both the Japanese voice actor and the English voice actor played, and that character's name fits into the boxes - first the Japanese name in kana and then the English name in letters. As an added hint, the pose in which the six characters appear is taken from the solution character's series.
(Note that names are different in different languages. In particular, a Japanese person's surname is first in Japanese but the given name is first in English. On the other hand, a Westerner's given name is first in both languages.)

English clue: MALE PRONOUN
ORE is the only word that's both an English word for "kouseki" and a Japanese male pronoun, so it is the answer to this puzzle.
