Honesty Sanders always liked magic. When he became friends with Deceit, he didn’t ask him if he believed in magic. He just... forgot all about magic.
Until one day where Honesty vanished from the mindscape all because of Corruption, he still believed there was magic inside of him. He even saved Deceit from dying.
When Deceit told Honesty all about his problems, he thought of something. Something that could help Deceit through his problems.
Something called... magic.
