The man from the prosperous urban area who has the lost swordsmanship with the sword passed down from generation to generation, the passionate man who fantasizes about the extreme world all day long, the cowherd who only teases girls all day long but can't control his shrinking physique, the proud and loyal dog who is only willing to give everything for his young master, the emperor who has already occupied the mysterious forest that everyone is in awe of, the king who often disappears and disappears, and -
That young boy who was obviously penniless but a thin beggar had the power to exaggerate everything and infect everything.
The five of them (←Hmm! That's right! It's five!) Crossed every corner of the continent, just to find the legendary Seven Sons of the Rainbow and get the legendary mysterious ring.
——It is said that with those rings, the whole world is yours.
——It is said that every ring has incredible power.
——It is said that these rings originally belonged to only one person.
Who is that person?
She is——
Sawada Tsunako.

Their journey has only one purpose - to save Princess Tsunako! (Pseudo)
