A kid obsessed with flowers becomes an accidental hero when he has to finish what his missing mentor started against resurrected demons. Three mismatched adventurers in a late 90s OVA that knows exactly what it is: small-scale, hand-drawn, unapologetic fantasy that trusts you to care about a flower merchant's apprentice more than the dragon he's chasing. The plot treads familiar ground (sealed evil, heroes who vanish, the kid who has to be brave), but the execution is pure OVA charm, earnest without trying too hard, strange without meaning to be.
A world once ravaged by demons found peace fourteen years ago when a boy named Zard defeated the evil dragon Diabolos. That peace shatters when the dragon returns, and Zard vanishes while riding out to meet the threat again. Years later, Kai sets out searching for answers about his missing best friend, carrying with him Zard's belief that humans and demons could someday live together without fear. His journey brings him alongside Izayoi, a peculiar young man who communicates with demons through pure emotion rather than words, and Gend, a scarred swordfighter whose Dark Elf heritage marks him as a survivor of an almost extinct race. As the three travel across a kingdom slowly being consumed by demonic resurgence, they uncover whether Zard's dream of coexistence was naive hope or genuine possibility. What begins as a search for one person evolves into a desperate race against time, where old grudges between species threaten to bury any chance at peace before it can take root.
