Upon a secluded island, a boy, his spirit bruised by sorrow, embarks on a fresh beginning.

Upon a sun-drenched isle, the boy whose spirit was fractured finds a tentative foothold in life.

Dust motes danced in the single shaft of sunlight illuminating the attic's gloom, where a forgotten chest was unearthed. Its presence was enigmatic, a silent question mark amidst the relics of bygone years.

The crew embarked on a quest for the keys to a long-lost treasure chest.

Hairi journeyed across the island, driven by the pursuit of a pirate vessel.

Hairi came to learn the tale of the Higenekos.

Hairi encountered a girl perched on the lighthouse, a solitary figure against the vast sky. She seemed lost in thought, grappling with the question of her own direction, uncertain of the path she wished to take.

Tsumugi resolved to construct a balcony on the lighthouse, utilizing the discarded Paringles cans she had diligently gathered.

Hairi and Shizuku searched for Tsumugi, but Hairi soon found himself separated from the others.

Hairi orchestrates a summer respite for Tsumugi that will forever remain etched in her memory.

Returning to the island, Hairi finds himself in a fresh beginning, encountering a girl he's never met before.

Hairi disregarded Ao's caution, choosing to re-enter the mountain after nightfall. It proved, unfortunately, that his concern had been well-founded.

Ao persists in her quest for the butterfly.

A considerable time has passed, and Ao and Ai have much to discuss.

On the island, Hairi encountered a solitary girl.

Upon reaching the main island, Hairi offered brief glimpses into his history.

Hairi and Shiroha must now make preparations for the ritual that approaches. Shiroha’s visions are growing sharper, more distinct with each passing day.

Hairi endeavors to fulfill Umi’s desire.

The heart of Umi’s summer aspirations begins to surface.

The appointed day approaches.

With the waning of summer, a subtle fading begins in Hairi’s mind.

The days lengthen towards autumn, and time continues its steady flow.

Nanami awoke on the island, a disorienting blankness clouding her mind. She had no recollection of her arrival, no memory of the journey that had brought her to this place.

Nanami received an invitation to join Shiroha and her classmates in crafting lanterns for the Natsudori ritual.

The truth of Nanami’s origins came to light.

The narrative of Umi reaches its conclusion.
