Manaka’s Feelings and Confusion

She is so innocent that she could even be caught by fishermen on the surface!
She has always depended on her close friends and often acts as the youngest sister of the group.
Her feelings become complicated when she starts noticing Tsumugu Kihara, who is different from the others because he is from the surface and treats her kindly.
She finds it difficult to understand her own feelings.
When asked if she likes Tsumugu, she says she doesn’t know.
When Hikari hugs her, she is so surprised that she runs away.
Even when Hikari confesses to her, she escapes, saying she doesn’t really understand how she feels.
Because of this, she sometimes makes things confusing for her friends.
The Ofunehiki and Manaka’s Sacrifice
During the Ofunehiki, a traditional festival, Akari Sakishima is supposed to be a sacrifice, but she accidentally falls into the sea instead.
Manaka bravely offers herself to the Sea God in Akari’s place, holding Hikari’s confession in her heart but never giving him an answer.
She is swallowed by the Sea God’s whirlpool and disappears.
Five Years Later and Climax

In the climax of the story, Manaka meets Hikari again, and finally, both their feelings reach each other.
This touching scene brings tears to many fans.
