Revenge of the Soul Eater: Cast Out as a Weakling by My Sword Saint Father Volume 4

At long last, after five years of exile, Sora returns to his birthplace-Onigashima-but he has no intention of reuniting with his former family! Rejecting Gozu and Cecil's attempts to reconcile, he heads straight to confront his father...and walks right into a trap! The Sword Saint's vassals have devised a plan to force Sora to face off against a formidable illusory beast known as a tsuchigumo in order to prove his strength. Sora scoffs and takes them all up on the challenge-until a new presence shows up on the island, so threatening that it stops everyone in their tracks! When total war breaks out in Onigashima, who will emerge victorious?!
