In this world, there exists mystical creatures known as "Yarimon".

Known as the loner protagonist with the weakest Yarimon... until now, that is.

In a surprising turn of events, the protagonist's Yarimon partner learned a godly-powerful move with a power level of 800,000 called the "Cheat Tackle".

With this, the protagonist's world completely changed, as this move will one-shot any opponent in battle (though it is only usable once per battle).

Of course, it would be foolish to believe that one can become the champion with just a single move. Therefore, a trainer must continue to hone their skills and diversify their strategies.

With that said, defeating my childhood friend for the first time is already a crazy accomplishment.

I can finally get back some of the money I lost to her...

Afterwards, I set out on an adventure after my childhood friend told me she was going on a journey and pressured me to do the same.
