Redo dream and the tournament

And his third friend redo rem had this back story:

Redo’s Story

Above the world floats an island known as Heavens Island.

Twice every year, a massive tournament is held. All powerful warriors—Melob Tree users, Corsal users, and other fighters—participate. The Warlords carefully watch these battles.

From each of the three parts of the world, two winners are chosen, making six winners total. These six are sent to Heavens Island.

On Heavens Island, winners receive luxury beyond imagination: giant houses, endless food, entertainment, and comfort.

Redo’s father was greedy but extremely powerful. He won the tournament and went to Heavens Island—but abandoned Redo and his wife.

Redo and his mother were left in poverty.

Redo now dreams of winning the tournament, reaching Heavens Island, and giving his mother a good life. He possesses shadow powers.
