Picture two characters:
The first - a fast talking, easily excited manic ball of energy with a tendencey to speak without thinking and a talent for rubbing people up the wrong way even if their heart is usually in the right place.
The second - a curmudgeonly, rule following type with a need for order and control who can come across as stuffy, even pompous though deep down they care. They do not however suffer fools lightly.
They are of course the perfect foils for one another, the red and blue oni, vitriolic in their dealings with each other yet bound together and despite their radical differences, come to embrace the bond between them.
