Mi-chan

　　　（　　 ▲∧
　　⊂、⌒⊃ﾟヮﾟ)⊃

Mi-chan (ミィちゃん) is an unusal derivative of Shii. Due to its appearance being a copy-paste of Shii, and the popularity of Shii abuse at the time, 2ch users originally assumed that it would be abused as well. However, Mi-chan was revealed to be an immortal parasite with the ability to infect and assimilate other characters.

Due to Mi-chan's similarities to Pororo, they often interact. Sometimes they hang out together and play with each other, or try to prey on each other. It is more mature than Pororo, and feels less guilt about eating people.
