Spiral: Bonds of Reasoning Vol. 10 (manga)

Hiyono’s gamble has bought Ayumu some time, but is ten minutes long enough to reason out an effective plan? Ayumu kicks his mind into overdrive, orchestrating a series of wave attacks designed to overcome Kanon’s incredible fighting skills.

But should any member of his already battered team miss their mark, it could mean death for them all. As the players move into position, Ayumu stands to face Kanon in what will be their final showdown.
