The first entry was mistagged recently. After checking the rest of the series's characters, I feel that most (and I do mean most) of the characters need a qualifier very badly, what's with the very short and ambiguous names they had.
(I use post #260115 as the reference for the characters)
Edit:
Also includes name changes for the two characters, according to the current (as of this writing) version of Wikipedia.
