Peekaboo is a young anomalous rabbit who is shown to almost never leave Haru Sagara's side. He is a supporting character who made his debut alongside Haru in "Episode 3: It Came From The Sea".
Species: Anomalous rabbit infant
Abilities: Strong bite
Type: Class C
Peekaboo is a small, round, white rabbit anomaly. He has small red eyes, large mouse-like ears, a bunny tail, and short stubby arms. He is typically held in a carrier sling across of Haru's chest.
When he was younger, he was the smallest amongst his brothers since his own mother refused to care for him anymore for looking more like his father.
Peekaboo is friendly and fun-loving. He cares about his friends and is just as outgoing as Haru is.
He also displays a mischievous side, sometimes teasing Haru by playfully biting him.
Despite being estranged by his own mother and brothers just for looking more like his father, he still felt the need to sacrifice himself in hopes of stopping a tree from toppling over them just before Haru saves them.
It is revealed in "Episode 22: Who Killed Robin? Act II" that Peekaboo used to be part of a family of five, which included himself, two older brothers, and his parents.
However, Haru theorizes that because Peekaboo was born resembling his father than his mother more, his mother and brothers estranged him from the family, whilst father Peekaboos normally do not take care of their young.
When Taiga breaks into Jabberwock, he ends up devouring one of Peekaboo's brothers, but before he could continue with the other brother and the mom, Haru stops him.
It is currently unknown what the status of the rest of Peekaboo's family is.
