The protagonist, Idyll, born into a family of knights, was a good-for-nothing, always compared to his brilliant older brothers.

His grades at the knight academy were lackluster, leading to his eventual expulsion. Simultaneously, his father disowned him.

Now free from all burdens, Idyll begins to seriously pursue the unique path he had long sought.

This was Bond Summoning.

A technique to summon things that don't exist in his world, through the bonds he forms with monsters.

Using this power, Idyll summons plastic bottles and chainsaws, fundamentally transforming his world.

As a result, those who expelled and disowned Idyll will face their comeuppance.
