Amayo

アマヨ

Amayo is Michiru Tsuki's ex-wife and Hikaru Tsuki's mother.
She welcomes Hikaru upon his return from his world trip, yet struggles to recognize her ex-husband, who has gained weight. She gets into an argument with him, insisting that there is something more significant than money; this only fuels her anger when he attempts to make amends by offering her material goods. As Ishidate is defeated, Michiru comes to understand that she was emphasizing that protecting his loved ones is the most important thing.
