Kaoru Yuuka

Notes:

What you see above is two incarnations of Kaoru Yuuka.
Kaoru Yuuka [Also known as Kamora Eudora] is one of the biggest self-insert multiverse sues you will find around. Not only have they have in over 30 fandoms, but the character has been paired with every Canon from said fandoms.
The character has no flaws, a barbie-esque body, a moving cowlick that expresses emotions, can juggle multiple careers[like being a j-pop star and a lawyer], and can turn any canon into a sue. Beware if you see her if your fandom.
