ファイ・ブレイン 最期のパズル

Daimon Kaito is a high school boy who loves puzzles. One day, the student council president gives him a mysterious mobile device that leads him to an underground ruin buried beneath his school. Together with his girlfriend Nonoha, he decides to challenge the "insolvable puzzle" hidden there.

However, the puzzle turns out to be one of the dangerous "Puzzles of Sage," created by the sinister organization POG. Kaito manages to solve it, but this victory marks only the beginning of a deadly puzzle battle against POG, where each new challenge could be his last.
