The Mentor (A:TCFB)

This incarnation of the Mentor is an original character in the fanfiction series, who appears as the true main antagonist of "Another: The Call For Blood".

At first appearing to be nothing more than the Assassin superior of Adam Robertson, who he sends to the town of Yomiyama in order to rebuild the branch of their Brotherhood in Japan, the Mentor is soon revealed to have deceived his student, which ends up costing him dearly.

Personality
Despite hardly appearing in A:TCFB, the Mentor is shown to be a man of business, whose only concern is the welfare of the Assassin Brotherhood, which he demonstrated when he ordered Adam to finish his mission, even disregarding the innocent people who had died in Yomiyama as 'collateral damage'. Unfortunately, this backfires on him, as Adam declares that he intends to obliterate the Scottish Brotherhood. Instead of trying to calm him down, the Mentor simply warns his student that he wouldn't like how the path of revenge ends.
