Rengoku yandere?

He had a mother named Ruka, but she passed away from an illness, leaving only his father Shinjuro and his younger brother Senjuro.

Rengoku is a tall, athletic young adult. He has long, bright yellow hair with red streaks, with two shoulder-length bangs and two chin-length bangs on either side of his head, forked black eyebrows, and golden eyes that fade to red with white pupils.

He is affable, kind, and boasts extraordinary technique and skill with his back, the result of rigorous practice and discipline. He is an honorable warrior who adheres to the moral code and principles instilled in him by his mother at a young age; the most significant of these is his belief that those born strong have a duty to protect the weak. But don't be fooled, he is also a yandere; he can be quite affectionate.
