Mind's referred to as the sun.
The canon name of the player in OMORI is Sunny.
"The sun shined brighter when she was here" is what is on Mari's gravestone.
a common dynamic between Heart and Mind is a sibling dynamic
Sunny is depicted as pretty stoic most of the time
Soul definitely knows how to tie a rope

Mind: Some people are like slinkies.

Mind: Not really good for much but bring a smile to your face when you push them down the stairs.
Soul: ...
Soul: Please don't push Heart down the stairs
