Ruu

ルゥ

Ruu is an alien infant from Planet Otto who possesses the ability to levitate and use telekinesis on objects. He develops a deep affection for Miyu and Kanata, viewing them as parental figures and frequently assisting them. However, he tends to employ his powers at the most inopportune moments, causing significant trouble for Miyu and Kanata. Despite being only a baby, he comprehends everyone perfectly. To conceal the truth about his identity from others, he is introduced as Miyu's younger brother, though Ruu denies this label and insists on calling Miyu "mama".
