This game is an RPG maker game.

The game is a basic RPG maker game with turn-based combat.
There is a pattern for each fighter; you have to play to your opponent's behavior, not just fight.

The game has a main story and a sub-story. As you progress through the sub-stories, you'll learn about the fighters' stories.

If you find the game too difficult, look around - there are sure to be NPCs giving you hints!
You can also earn in-game money to improve your skills or increase your HP MAX, which will give you an advantage in battle!

When you win or lose a battle, you get a contextual CG, which is basically in every battle, and subquests also have CGs.

I did my best, but you might see some flaws.
I hope you enjoyed playing it!
