Who is Sangonomiya Kokomi? – Character Lore and Background

Sangonomiya Kokomi hails from the Sangonomiya Clan, a bloodline that traces its origins to the will of the Serpent God, Orobashi. According to legend, Orobashi guided the people of Watatsumi Island to the surface, offering them a new home. However, the god was later slain by the Electro Archon, Raiden Ei, during a past conflict. Following Orobashi’s demise, the Sangonomiya Clan became the island’s steadfast protectors, ensuring that its people endured even in turbulent times.

Kokomi, as the current Divine Priestess of Watatsumi Island, not only handles religious and ceremonial duties but also serves as the island’s highest-ranking strategist. During the events of the Vision Hunt Decree, she took command of the resistance forces, cleverly maneuvering around the Shogunate’s superior military strength to secure key victories. Despite her young age, her inherent intellect and tactical acumen earned her the unwavering respect of her people.

Sangonomiya Kokomi’s Combat Role and Abilities

Kokomi is a 5-star Hydro Catalyst user who specializes in healing and sustained elemental application. Unlike most Catalyst users, who focus on ranged attacks, Kokomi’s kit encourages a close-quarters playstyle where she constantly applies Hydro to enemies.

Element – Hydro

Kokomi wields the Hydro element, allowing her to synergize exceptionally well with Cryo (for Freeze teams), Electro (for Electro-Charged reactions), and Dendro (for Bloom-based reactions in later updates).

Weapon – Catalyst

Using a Catalyst enables Kokomi to deal consistent Hydro DMG with all of her attacks, making her an effective enabler for Hydro-based reactions.

Kokomi’s Abilities Breakdown

Normal Attack – The Shape of Water

Performs up to three consecutive attacks in the form of swimming fish, dealing Hydro damage.
Charged Attack: Consumes stamina to deal AoE Hydro damage.
Plunging Attack: Deals AoE Hydro damage on impact.

Elemental Skill – Kurage’s Oath

Summons a Bake-Kurage, an aquatic jellyfish that periodically heals party members and deals Hydro damage to nearby enemies.
Healing is based on Kokomi’s Max HP, making HP her most valuable stat.
Activating this skill applies the Wet status to Kokomi.

Elemental Burst – Nereid’s Ascension

Kokomi dons her ceremonial robes, boosting her Normal and Charged Attack damage based on her Max HP.
Her attacks heal all nearby party members for a set amount based on her HP.
She gains resistance to interruption and can briefly walk on water.
The effect ends when she leaves the field.

One noteworthy aspect of Kokomi’s kit is that she has a unique passive ability that decreases her Crit Rate by 100%. This means she cannot score critical hits, pushing her towards a playstyle that relies entirely on raw damage multipliers, healing efficiency, and Hydro reactions.
