Synopsis
After Yuuta finally becomes aware of Sophia's love for him, he seeks advice from Shinka Nibutani and Kumin Tsuyuri. Satone has assured Yuuta that she has recovered from her heartbreak but Shinka informs Yuuta that Satone's lying and reprimands him for being so dense. Kumin then tells Yuuta that Shinka only became upset because she loves him and all her friends and only wants the best for them.

Meanwhile, Rikka who has caught a cold from the Bon festival's rain, is still keeping the purpose behind her nightly outings a secret, to Yuuta's worry and dismay. Shinka, as Mori Summer, encourages Satone to seek out and defeat her true enemy, who Satone concludes to be Yuuta. As she challenges him, Kuzuha Togashi informs Yuuta that Rikka has gone missing.

Remembering a note that holds instructions on awakening the Dark Flame Dragon that was written when he was in middle school, Yuuta realizes that Rikka had been out at night trying to fulfill these instructions the whole time. Worried for her health, Yuuta pursues Rikka, and Satone follows. When Yuuta finds Rikka, she tells him that she wanted to awaken the Dark Flame Dragon in order to affirm their lovers' contract and prove her love for him, revealing that the presence of Satone diminished her faith in their contract and left her apprehensive. When the Dark Flame Dragon is finally awakened, Satone battles it, overcoming her heartbreak and afterward becoming renewed. Yuuta alludes to Satone's natural laws about saying goodbyes. Satone then smiles and bids him farewell.
