Inferno

Inferno is the final stage in Episode 10: Angels, Demons, and Humans in Disgaea: Hour of Darkness, and in Episode 3: Chronicles of Etnarnia in the remakes' Etna Mode.

Story
They finally catch up to Mid-Boss and they fight over the picnic basket. However, it seems Mid-Boss has already consumed all the contents. Gordon tries to leave. But Etna helpfully points out that will be rather hard, seeing as their space ship is in pieces due to their crash landing.

Etna Mode Story
Etna finally finds what she's looking for, only to be stopped by Justice Flonne again. They argue and suddenly Flonne starts feeling unwell. A dark aura engulfs, changing her into Dark Flonne. After the battle, Flonne returns to her normal self. However, Maderas took advantage of their battle to steal the lost memories. Vyers shows up, ready to save the damsels in distress, and claiming he will take care of it.
