Spiral, Vol. 7

Though Ayumu is steadily losing confidence, the Blade Children are
gearing up to act against Kanon's threat. Claiming the newspaper room
as their temporary headquarters (much to Hiyono's dismay), Rio,
Kousuke, and Ryouko organize their offensive with an array of modified
anesthetic weaponry to take down their former friend. But when Eyes
makes an unexpected recovery, Kanon is pressured to make his move,
putting Ayumu and the entire school in danger. How will Ayumu's logic
and reasoning fare against Kanon's brute violence?
