Otsuu and Nightmare Jack are paired together in battle. Because of this, they can act twice in a single turn, so they hold the key to turning the tide in battle!
When playing as Otsuu and Nightmare Jack, players are able to input two actions and switch off between the two characters. Otsuu can use one turn to attack the enemy, while Nightmare Jack can use the second turn to use his Purge Abilities. Or even have one character perform two actions - it's up to you!
How will you choose to use them in battle?
Using a certain command in battle will engulf Nightmare Jack in madness that will eat away at his sense of restraint.
Once Jack is completely taken, he will transform into a rampaging monster - "Ripper Jack."
Jack can return to his normal state as the turns progress, but until then, he will use his Nightmare powers to strike at both enemy and ally!
Jack and Otsuu are connected through their minds.
Because of this, Jack's madness accumulates a large amount of Corruption within Otsuu.
It could be very well possible that Otsuu enters Blood Skelter right after Jack goes mad, so having Otsuu use her special command, "Counseling," before Jack turns into Ripper Jack can help avoid such a situation.
