アルカンシエルの魔獣 / Arc-en-ciel no Majuu (Beasts of Arc-en-ciel)
It is a world of beasts and magic.
The once glorious land is slowly coming to an end as it is being consumed by mamono and miasma.
One day, a lion boy meets a canine boy who has amnesia.
He was carrying one of the seven colored keys, which are said to grant the wishes of those who collect them.
Thus, the boys' adventure to save the world begins.
