At the start of the summon, a dark portal forms out of the ground and shoots out a solid rock. Out of the rock bursts the Seru, Nighto, which shrieks and then closes up in its shell. Soon after, Nighto opens up and makes a strange sound from its mouth, unleashing sound waves that target a single enemy. With bad luck, the sound waves have no effect on the enemy. However, they can also charm the enemy or instantly annihilate it.
- Hell's Music can confuse or instantly kill a single target. However, it can also have no effect and account for a wasted turn as it does no damage
- As Hell's Music levels up the chances of confusion or annihilation will rise
- Hell's Music can instantly confuse or kill the boss Berserker
