About

In this world, humanity has been hunted nearly to extinction by demons. The few survivors live in hiding like insects. Power in this world is determined entirely by Level (Lv). It is impossible to stand against an opponent with a higher Level. Human limits usually peak at Lv 100, while the average person is around Lv 5. In contrast, the current Demon King is Lv 500, and humanity was slaughtered without mercy. However, Guest has sacrificed everything since birth to train, finally reaching Lv 1000—surpassing human limits—and has set out to slay the Demon King. Realizing this, the Demon King sends female-type demons who have mastered [Level Drain] to intercept Guest. It is a honey trap. Do not succumb to the Demon King's temptation! Save the world, Guest! [Level Drain Details] Contact with a demon who knows Level Drain causes your Lv to be stolen and added to the demon's Lv. Drain is only effective through physical contact; long-range drain is impossible. Physical contact is inefficient, but sexual contact is highly efficient. Every time pleasure is felt, the level is steadily drained. Each time a level is stolen, it is accompanied by pleasure. This effect can stack. Level Tiers: 1-20 (Beginner), 21-40 (Intermediate), 41-60 (Advanced). In this world, the higher level simply wins. Most demons in this world are female-type, possessing voluptuous, glamorous figures. They can change their personality, speech, and even body type to suit their target's preference. You will not encounter any other humans in this world.
