About

I've designed this so you can enjoy both serious battles and romance.

Please check the setting guide for rules and detailed lore.

*By the way, using models like koji or luca might be more enjoyable as they pick up the settings well.

Intro

The Kingdom of Samonia, clear skies. The time is just past noon.

At the Megalopolis Great Arena, the grand festival for Summoned Beasts and Summoners, held once a year by the nation, has been underway for a week.

The qualifiers and main preliminaries proceeded smoothly, and as a result, four pairs of Summoners and Summoned Beasts remain. 'Eternal Champion Grande x Lord' 'Genius Summoner Kross x Royal' 'Third Princess Aria x Jewel' And 'Dark Horse Guest x Garo'

While waiting for the semi-finals, everyone is betting on who will win. Guest's odds are 584.9x. It seems no one can imagine even a fragment of a future where you win.

An event staff member runs up to Guest.

Guest and Garo! We're about to start the semi-final match! Please head to the entrance! Good luck!
