Ohm

People discovered a little life of unknown origin - Ohm on the Dragon Star. He comes in many sizes and shapes. He likes to follow people, is smart and loves to act coquettishly. Because they always cried "Oh", people named him "Ohm". Ohm's lifespan and habits vary depending on the species. Because of his cuteness and lack of aggression, people adopt him as a pet or even a good friend.

MOMO

MOMO is a robot living on the O2 planet. As stated in the background of the story, the saints of the Galactic Curse Sect spread Ohm, an unknown creature, in the galaxy. Biological creatures make people listless, and all nine planets except O2 are infected. Scientists from Philosophy Star say that the O2 planet can escape this disaster through the O2 (oxygen) produced by Jam (ensemble). MOMO is responsible for converting people's Jam into O2, so MOMO's role is very important! MOMO is in urgent need of everyone's help. Only our Jam (ensemble) MOMO can produce O2 and wipe out all the ohms!
