The only way to escape the game is to help the male lead and main villain, the [Lord of Nightmares], and his comrades to defeat the final boss and see the ending! But… [The Lord of Nightmares feels deep anger at your words.] [The Lord of Nightmares feels a strong murderous impulse toward you.] It feels like I'll be killed by the sociopathic male lead's hand faster than I'll see the game's ending! On top of that, the quest difficulty keeps skyrocketing... Is it even possible to see the ending, you bastard developers!
