Portal Koi

Portal Koi is a fish-like creature that can be caught in Torii. It is tied to fishing rather than normal world exploration, and wearing the appropriate item increases the chance of catching it.

Aside from being a catchable creature, the available sources do not provide any further confirmed gameplay details about its behavior or rewards. It is specifically noted as requiring fishing in Torii, so players looking for it should focus their efforts there and use the chance-boosting gear to improve the odds.

• Can only be fished in Torii.
• Wearing the relevant item increases the catch chance.
