Cuckoo

In a dream, Cuckoo is recalling a day in the park where he is flying a cardboard airplane. He looks around and wonders where everyone is, noticing his parents are gone as well. Suddenly a girl that appears to be a younger Yuna grabs his arm with tears in her eyes. She hugs him and the boy suddenly realizes there are dead bodies surrounding them. Then, a black-haired man with a bloodied shirt carrying a pipe is towering over them, yelling out that it "serves you right". Cuckoo then finds himself woken up by Crow.

The story seems to suggest that Crow was actually the murderer of Cuckoo's parents. Cuckoo, when he knows Crow is released from jail, prevents him from committing suicide and they end up becoming roommates. It is unclear if Cuckoo has ulterior motives for following Crow around. Likely Crow is also responsible for the death of Yuna's parents in the park. The man in the fur vest is seen in one scene hugging the two children during the traumatic event (refer to Ch. 36). There is still a lot of uncertainty regarding how this man and Bustard are connected, since he eventually tried to have the man killed. However, it may be possible the man in the fur vest survived after all, because he was first seen in Ch. 03 watching Yuna and Onyu walk away together.
