Stand By Me Episode 13

Birdy and Tsutomu head to the Lost Bird to figure out a way to purge the Ryunka out of Sayaka's body. The two were able to do so, at the cost of Tsutomu's own body when he sacrificed it to allow Birdy to kill him again and purge the Ryunka parasite out of his body with Nejula in charge of containing it. The Japanese government had covered up the events as the JGSDF had mobilized in Roppongi. Due to the events, Sayaka loses some of her memories including her encounters with Tsutomu. Birdy once again merges with Tsutomu until a new body can be readied. Meanwhile, Gomez and his boss Revi had a conversation about whether Birdy is a threat, with Gomez telling Revi to take some precautions against her.
