Isekai HKV is a 2D top-down pixel-art roguelike game themed around Vtubers traveling to another world,
inspired by MegaBonk and Holocure.
Players take on the role of the hero “DD”, venturing deep into the Demon Lord’s army territory. Fight side by side with companions(Vtuber), face endless waves of enemies, defeat the Demon Lord, and reclaim the power the Vtubers have lost!

Attacks are automatic—you only need to move and dodge (Space).
Defeating enemies grants EXP to learn otherworldly magic. Opening chests grants otherworldly item skills, giving you various abilities.
At the base, you can use “Unlimited Gacha” to obtain Vtuber companions and bring them into stages as AI teammates!
Each Vtuber has unique innate abilities, attack patterns, and stats, shaping your tactical choices.
After defeating a stage Boss, you can reclaim the power the Vtubers have lost and strengthen them!
In each stage run, players can unlock companions’ innate abilities by upgrading certain stats, gaining new passive skills.
Each stage features many otherworldly invasion events that spawn randomly at specific times, offering different arena effects and modes—such as timed capture, calamity triggers, summoning otherworldly monsters, and more.
By clearing these challenges, players gain upgrades. You’ll need to keep exploring the map to discover these areas, take on invasion events for extra rewards or abilities, add unpredictability, and test your real-time decision-making.

In VTuber culture, DD is a very common term that comes from the Japanese phrase "誰でも大好き" (Daredemo Daisuki), which means "love everyone." Simply put, DD is used to describe fans who like many different VTubers, rather than focusing their support on just one VTuber.
