Mayuka is a very sweet person. She acts like a kid even though she looks 16. She has a sweet kind and caring look, but if you make her mad, watch out. Her and Ryoko fight a lot (more gruesome than how Ryoko and Aeka fight) but that might be because Ryoko thinks Mayuka came to kill Tenchi. Actually, that's true, but poor Mayuka didn't know it. Mayuka is clueless, but more like a child's type of clueless. She even acts like a Child. She constantly calling Tenchi Papa, and hangs all over him. But behind her sweetness, she does have a temper when Ryoko accuses her of stuff.
