Kernel Hearts Characters & M.A.H.O.U Unit
Every character in the Kernel Hearts game: which floor they join, the elemental weakness to exploit and the chip loadout to bring.
Quick answer: Four playable characters — Fernet and Spika unlock on Floor 1, Laika and Dolce on Floor 2 — each with an element (Fire/Ice), a weapon style and a full guide page. The roster table below lists every kit at a glance.
All Characters (4)
Fire-Weak Characters
Fire-weak characters deal double damage to Ice-attuned enemies. Load them with Ice-coated attack chips for maximum efficiency on the lower floors.
| Character | Floor | Weakness | Recommended Weapon |
|---|---|---|---|
| Fernet | Floor 1 (The Outer Gates) | Fire | Iron Sword |
Ice-Weak Characters
Ice-weak characters counter Fire-attuned biblical angels.
| Character | Floor | Weakness | Recommended Weapon |
|---|---|---|---|
| Spika | Floor 1 (The Outer Gates) | Ice | Hunter Bow |
| Laika | Floor 2 (The Heavenly Courtyard) | Fire | Iron Sword |
| Dolce | Floor 2 (The Heavenly Courtyard) | Ice | Hunter Bow |
How Elemental Weakness Works
Every enemy in Kernel Hearts is attuned to one element and weak to its opposite. Hitting a weakness doubles damage and accelerates the transformation gauge. The character table above lists the correct element for every unit. Bosses follow the same rule — the Floor 1 Guardian is fire-attuned (bring Ice), the Floor 2 Guardian is ice-attuned (bring Fire).
