Kaname Isaki hails from the submerged village of Shioshishio and stands out among the main cast as the most emotionally grounded of the group. Gifted with a natural ability to read between the lines, he often senses the unspoken romantic feelings swirling among his friends before anyone else does, quietly watching over them with a big-brother warmth. Though his demeanor is relaxed and unhurried, he proves remarkably bold when it comes to matters of the heart—becoming the first in the group to confess his feelings openly. After awakening from hibernation and navigating the changes that time has brought, he and Sayu forge a profound and lasting bond.
