His older brother took the Saintess and disappeared.
The heroines left behind were supposed to be fine on their own.
They weren't.
After defeating the Demon King, Leon abandoned his former companions and returned to Earth with only the Saintess, leaving the other legendary heroines behind with severe physical and psychological wounds.
Evan, Leon's younger brother and a quiet alchemist living in a rural village, only treats them because he can't stand by while they're suffering.
As their bodies and minds slowly recover under his gentle, unconditional care, something unexpected happens.
The better they get, the less willing they are to leave Evan's side.
