Upon arriving, he finds the remote island to be overrun by tourists viewing the Tango star cluster. Uehara visits his mother to ask for help, but she tells him he is on his own. As Uehara, who has a communication disorder, wanders the island, he runs into people from his childhood, including Shinjou Kanako, his first love. She helps him collect a rare fire ant species, but her husband Nishihara takes her away. Uehara runs into a nearby forest and watches them have sex. As the Tango cluster becomes visible, light emits from it, and Uehara comes across an otherwordly insect that bites him.
