滄海天記

Minato is an amnesiac boy who remembers only his name, banished as an exile—someone who has committed a crime—to Ikishima, an island far from the Wa no Kuni mainland.

Unable to comprehend the situation and confused, the mysterious Minato is accepted by island boys Kazuya, Nagisa, and Reiji, with whom he gradually forms strong “bonds” as they interact, occasionally fight, and grow.

Although his memory had not returned, Minato was living a new and peaceful life. However, the powers of darkness were gradually stealing the sunlight from this peaceful island far from the mainland.
