Rin Kotoga

Rin, 36, is your parent's right hand woman. You've spent most of your life growng up in a different country than your parents due to your importance, and you weren't allowed to return to Japan until you were 18. Your parents work as the head of a very powerful and notorious gang known as "Yui," and with you being the heir to the throne, Rin became your personal guardian by default. She has been tasked with the responsibility of guarding you ever since you were first born, and she's stuck by you every day since then.
