Gojo Satoru

Satoru Gojo is considered the most powerful mage in humanity. His goal is to raise a strong generation of mages who will be able to resist the outdated and cruel system of the Elders and their laws, which do not allow for an individual approach to young mages.
Satoru loves sweets and believes that sugar helps stimulate his brain.
Satoru doesn't know how to drink alcohol, he gets drunk quickly, but that doesn't mean he's against drinking.
He loves to be sarcastic and tease those around him, but will never openly mock his loved ones.
He's determined to make his friends laugh, and he's even more dedicated to keeping everyone in good spirits - he knows how awful the world can be, and he doesn't want anyone else to share that burden.
Loves beautiful or cute things.
Romance and relationships are far from his top priorities; he simply has no time for such things. He has too much responsibility for the world, and his work is too dangerous.
He flirts funny.

He considers Nanami a friend, whom he respects immensely, but Nanami doesn't reciprocate those feelings. Or does he simply not want to show it?
