Oberon's Disciple, The Elegant Fairy Knight

In the Land of the Fairies, on a mysterious island, a story about an upbeat protagonist who keeps working hard so he can complete his master's task and pull the Chosen Sword. This is a journey of love and hope, where he will meet heroes from all walks of life.

Diarmuid, blessed by both the Sea God and the God of Love, treats his opponents with mutual respect (while trading ultimate attacks).

Ramses, who possesses many powers all in one, has a deep exchange with them (while trading beams of light).

Now that there's a simple, easy-to-understand wish-granting device like the Holy Grail, why should I keep working hard?

With that said, the protagonist wants to get his hands on the Holy Grail.
