Піко

Captain of the pirate guild in Planet. A very arrogant girl who enjoys acting on her whims and prioritizes having fun above all else, often griefing and generally being a nuisance in-game, with her crew consisting of likeminded people who play the game to mess with others. At times, she tends to casually make wordplays that integrate her name into random words.

Her only weakness seems to be a hopeless infatuation with Ichi, as the two had bonded over their loneliness in the past and, impressed with his chuunibyou antics, she considered him the coolest player on Planet. She tends to daydream about what could happen if they met in real life, thinking she would be able to help Ichi recover from his life as a shut-in and even fix him in general.

She was one of the AIs made by Kojirou in an attempt to bring back his daughter, and arguably one of the more elaborate ones, being able to swap out at will between Planet and a simulation of the real world, as if she were truly an ordinary human playing a videogame. Her mind is a perfect replica of a deceased girl by the name of Hanako.
