The big question going into this week was “What Now?” Would Riri and her Legion try to find a way to bring Yuri back, or would she accept and process her loss? This is answered pretty quickly: Yuri is gone, and she’s not coming back. As a formality, Riri is serving a week in solitary confinement.
Even her Schutzengel Yuyu can only visit her for ten minutes. It’s clear Riri’s building a hard shell in which to put all of her regret and sadness, and Yuyu wants to do something about it. So she asks the rest of the Legion to help her look for her missing four-leaf clover hairpin, which she lost in the battle.
They all think of ways their perception-based rare skills can be combined and experiment over the next six days, but without success. They mostly end up exhausting themselves and requiring long soothing baths to recover, but no one wants to give up.
During one of those bath sessions, other Lilies learn what Riri’s Legion is up to, and they want to help contribute if they can. Meanwhile, Kaede seems busy using the crafts workshop to create a new four-leaf clover for Riri.
On the seventh and final day before Riri is released, Yuyu and her Legion are shocked to find virtually the entire school has come out to the beach so they can all combine their magie into one massive ultra-precise search net.
It works: the location of the pin is determined, and Kaede rides on Thi Mai’s back and they race out to the open water to recover the pin…at the cost of getting very cold and wet and needing to sit by a fire afterwards.
When Riri emerges from her cell, she’s surprised to find not just her Legion members, but all of the other Lilies who helped out and were concerned about her. Kaede presents the four-leaf clover she made, and Riri recognizes it as a fake, as hers always had a crack in one leaf.
Kaede owns up to having found the genuine article early in their weeklong search, but it was so badly damaged she feared presenting it to Riri would do the opposite of cheer her up, so she spent long nights crafting a new one from scratch.
Kaede is contrite for duping everyone, but Riri gives her a big hug, thankful for her and everyone else’s efforts on her behalf. Then, despite being happy, tears start to fall, and before long she’s bawling her eyes out. Yuyu is glad she’s letting it all out; its a catharsis Riri’s imprisonment had unnaturally delayed.
Now that she’s free, Riri can finally visit Yuri’s grave and pay her respects, and the subject of Yuyu’s Schutzengel Kawazoe Misuzu comes up, with regard to how Yuyu managed to get over her death. Yuyu says it simply takes time and the acceptance that the past can’t be changed. Then the “ghost” of Misuzu appears and speaks to Yuyu (Riri can’t see her).
This is an odd coincidence, because a CHARM has been recovered from inside a Huge five months ago, and Moyu determines that its owner was…Kawazoe Misuzu. Is the ghost just in Yuyu’s head, or is it a product of Mizusu’s CHARM somehow “influencing” the Huge?
