|“||Hmm... What's the difference between an orca and a forka and a storka...?||”|
–Peraco, Ice Watching: Round 1
|Relatives||Three Younger Siblings|
Peraco has long, dark grey hair with yellow stripes on the inner parts, and golden eyes. She wears a penguin cap, what appears to be a black hoodie with a penguin-like tail or backside behind her, a white dress with yellow stripes, orange stockings, and black boots with yellow spots on the side. Her hands are instead flippers.
Peraco is a peculiar individual, often "thinking about worthless junk" ( as stated on Ice Watching: Round 1), and has several mysterious things within her home. She is peppy and carefree, and even stated to be "very lucky".
Peraco is not easily intimidated; bold enough to tell Idate that his fly is down, and hardly shows signs of fear when the orca attacks her and Shirogane, only presenting shock when Rocma is dragged underwater.
She is an emperor penguin living on Iceberg Isle with her three younger siblings. She is frequently seen tending to the young ones, such as her siblings and Mafuyu.
- Ice Scream - supporting character
- Mogeko Castle - appears on a TV screen.
Ice Scream Cast
Shirogane is a good friend of Peraco, and her neighbor. Though she is prone to berating him, she has good intent and looks out for him just as well (e.g. demanding a "thank you" from Rocma after Shirogane saved her from drowning). Shirogane has saved her from Idate once before, and has been seen taking walks with her.
Yukisada is Peraco's friend and neighbor.
Rocma is Peraco's friend and neighbor. Though Rocma continuously denies Peraco's invitations to playdates with Mafuyu and her siblings, they are on relatively friendly terms.
Mafuyu is Peraco's friend and neighbor. Peraco often cares for and plays with her alongside her siblings when Rocma is unavailable.
Rock is Peraco's friend and neighbor. While she tends to annoy him, they are not on bad terms.
Idate is an enemy of Peraco. Idate has attempted to eat her when she was taking a shortcut with Shirogane, but does not seem to show much fear of him. Even as Idate was battling Rocma, Peraco blatantly gives her own comments during the fight. Peraco is one of the handful of people who is daring enough to make a mockery of Idate.
Sunosan is Peraco's neighbor.
- There is an underground cellar under Peraco's house, which is rumored to be a secret passage.
- There is a mysterious flower that is rumored to move during the night on the left side of Peraco's television set.
- In Ice Watching: Round 2, she is said to love sledding, but loves skating the most.
- Her name, "Peraco," is derived from "Emperor penguin." 
- "Um, Shirogane?! My siblings JUST built this! How dare you besiege it?! Get out of there!" (To Shirogane, who is inside her siblings' igloo – Ice Watching: Round 3)
- "By the way~ No one pointed it out to you, so I'll just mention it now. Your zipper's undone." (To Idate – Mini-Comics)
