The Right of Friendship
As Kaito remains unconscious in hospital, Cubic is invited by Rook to take on a puzzle and accepts it, wanting to prove his friendship to Kaito. He comes to an abandoned military base where a different POG Giver gives Cubic a math puzzle to solve, where his failure will result in him being blown up by a tank. Meanwhile, Kaito regains consciousness and explains his situation with Rook to the others. Cubic is given the chance to escape, but he remains determined and manages to solve the puzzle at the last second. The Giver reveals that Rook made the puzzle when he was five, which makes Cubic feel unworthy of being Kaito's friend in comparison.

Phi-Brain: Puzzle of God
Kaito Daimon would be a completely average high school student except for one thing: he's a 'demon' at solving puzzles. Kaito is so brilliant, in fact, that when he's asked to take some 'special' tests of his unique ability, he immediately suspects that the test itself is a test. Kaito suddenly finds himself caught up in a lethal Philosopher's Puzzle made by the sinister group POG, a murderous maze of trap upon trap, where failing to solve the secret correctly will result in death! Fortunately, Kaito's skills prove up to the first test, both for himself and his childhood friend Nanoha, who is also caught up in the deadly scheme. But now that he has been designated as a Solver, he is pulled into a new life where he must travel the world with other Solvers, attempting to solve the latest deadly riddles left by POG. There's a new conundrum around every corner and each deception could lead to death, but once a riddle has been posed, you can count on Kaito to unfold, unravel and unlock it!
