Shin Megami Tensei III: Nocturne
Yomotsu Ikusa's name was shortened to Ikusa.

Persona 4
Can be obtained from Shuffle Time in Marukyu Striptease. This is the only Persona that when called out (hitting a weakness or critical hit), does not have it's full name read out - instead, the protagonist only says "Ikusa!".

Devil Survivor: Cverclocked
He appears on Day 4 as an optional boss labelled Netherworld Soldier. He is in Aoyama Cemetery, amassing an army of the dead, ordering them to go into town and avenge themselves. The protagonist and his friends will try and stop them, but right before the fight a man will appear and accuse them of summoning the demons, ensuring they can't let any of the undead invaders escape, making the ensuing fight much harder. Ikusa will summon Loas, Legions and Pyro Jacks to fight; some try to fight, but most will try to get around to the exit; this will cause you to lose the fight. The boss and his demons are quite overpowered and should be attacked on a second playthrough. It's also recommended you save Midori in order to ease the burden of the fight with a fourth team.
