Riri is slacking off now that Yuyu has accepted her. Yuyu asks Riri to form a legion to keep her active, expecting her to fail. But when Riri starts actually recruiting members, Yuyu may be in for more than she bargained for.

When Yuri's origins are revealed, she is classified as a Huge. Riri flees the academy with her, but orders are issued for their capture. What will the other Lilies choose when ordered to hunt one of their own?

As Riri and the others continue to grieve, Yuyu isolates herself, tormented by visions of Misuzu. As the Huge attack Yurigaoka as they never have before, Yuyu is forced to question the truth of her relationship to her late Schutzengel.
