Ayumu Narumi aggressively pursues his goal to unravel the mystery of the "Blade Children." With every step he takes, though, the path to the truth becomes more treacherous as a conspiracy is revealed. Could it be that Ayumu's fate was intertwined with that of the Blade Children even before his journey began?

With Kanon ready to start hunting down the Blade Children one by one, Ayumu finds himself in the thick of things as the hunter vies for his allegiance... at gunpoint! But even when both Eyes and Rio are in his deadly sights, Kanon's plans are thwarted by his own promise to not harm any non-Blade Children...

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...

When Hiyono turns the tables on Rio and Kousuke and demands a rematch for Ayumu, she ends up getting kidnapped! However, it looks like there'll be a rematch after all. In exchange for his trusty information dealer, Ayumu must hand over Hiyono's hard evidence against the Blade Children...in one of Rio's devilish games! Will Ayumu's pride be his downfall?

The battle with Kanon may be over, but it's going to be some time before Ayumu and the others fully recover from the ordeal.

Hizumi makes his final plea, begging Ayumu to accept the fate that has been forced upon them.

After all he's been through, Ayumu certainly intends to meet his brother,...

Despite thorough planning and preparation, the offensive against Kanon is not going well. Bruised and broken, Rio, Ryouko, and Kousuke are no closer to reaching Kanon than when they started. But Ayumu's trusty information-gathering sidekick is ready and willing to help out. Now they know where Kanon...

Hizumi's "happy high schooler" facade begins to crumble as Ayumu confronts Kirie about Hizumi's cheerful acceptance of the fate that awaits him. Big brother Kiyotaka has always cast a shadow over Ayumu's life, but what kind of despair has Hizumi known that would make him so ready to die?...

Ayumu prepares to leave the hospital, still mulling over the murderous role fate has for him to play. But if Hizumi is destined to die at Ayumu's hand, why does he seem so eager to be friends? Far from bloodthirsty, the good-natured Hizumi has been living in Ayumu's apartment since the Kanon incident...

Kanon is startled by the sudden arrival of Madoka Narumi, but not so much as to shake his aggressive offense. Still, it's enough to give Rio the chance to rescue the captive Ayumu. Free at last, Ayumu must face the difficult decision that lies before him. Is his only option to kill Kanon? As the Blade...

When one of Ayumu's teachers promises to give him a few clues about the Blade Children, the deceptively cute Rio, one of the Blade Children herself, ruthlessly murders the man in broad daylight. Faced with another brutal murder to solve and one step closer to finding out what the Blade Children really...

Hiyono's gamble has bought Ayumu some time, but is ten minutes long enough to reason out an effective plan?
