Waiting in the Summer Season 1 Episode 8

Senpai's In Trouble

After Ichika enjoys her first Japanese festival, Lemon pops out of nowhere to challenge everyone to a test of courage at a dark shrine. During the test Rinon appears to Ichika, telling that an emergency beacon has been activated. True enough, a League lifeboat (a rescue drone) comes to rescue her (it's more of taking her by force), but Ichika says she has still a lot to do. Then again, when Kaito hears Ichika scream, he rushed to where she is, abandoning his partner Kanna. Even with the help of Rinna, one of Ichika's machines, Kaito dies rescuing "the one he loves." Ichika, however, manages to reverse Kaito's death. Kaito awakens and sees himself with Ichika inside a ball of light, and mysteriously returning to the same spot. Everyone catches up to the two and sees Ichika incessantly apologizing in front of Kaito.
