Doubt season 4 character profiles 

Makoto and dear unstable mommy...  For context: Makoto's mother is described in canon to be "a pale-skinned beauty", almost like a ghost, and seems to follow around Yuu-kun around in secret but he usually notices anyways and lets her... I couldn't let go of this canon info, so I assume she must be pretty unstable to always be so fixated on caring for Yuu-kun... it must be because he’s the only family left for her after the divorce, I imagine she must be super fond of Izumi as well to the point where she even has him take care of Yuu-kun at school...
