Orca is a supporting character in Wadanohara and the Great Blue Sea. While his talk sprite is named as "Orca" in-game, Mogeko has given him the name Idate.
Orca is tall, and has an intimidating look on his face. He has cropped black hair with two white ovals on the sides, giving him a more orca-like appearance, along with a tall black dorsal fin on the top of his head. He wears a black business suit and a grey shirt under with a tie, black pants, and black gloves and shoes. He almost always has a smirk on his face, unless he's confused or disappointed. He is also sometimes shown holding a cigarette.
Orca tends to be very cruel and a bit sadistic, saying he "plays" with others as a term for beating up. He's also a bit derogatory, especially to sharks, calling them "stupid" and "just fish". However, he can also be helpful, as he helped Tatsumiya escape (by Wadanohara's request, although he had claimed he had nothing else to do).
- He has appeared in a few of Mogeko's illustrations, and is even a character in one of their side comics, Ice Scream.
- This could be an indication that Idate is one of Mogeko's favorites among their characters.
- He was seen receiving cigerettes from Nekoyama in Ice Watching, and this is the only record of the two interacting so far.
- In the Japanese version of the game, he's known as "Syachi", which is simply Orca in Japanese.
- He is known to like witch meat, even asking Wadanohara if witch meat is delicious.
- Mogeko has stated in an omake that he's a "fucking huge dick."
- In Bad End 1, he eats Wadanohara.
- Orca is actually weaker than the 3rd fight with Samekichi.
