Onikami

Onikami Legacy is a Demon Slayer-inspired action RPG on Roblox developed by Redevil Studios, with over 12.9 million visits and 59.3K favorites across three years of continuous updates since its February 2023 launch. Players choose to become a Demon Slayer, a Demon, or a Hybrid and battle through an open world built around quests, boss fights, and PvP combat.

New players spawn at Otama Village and complete the Final Selection trial before the full map opens. From there, your race choice defines the entire experience:

• ⚔️ Fighting as a Demon Slayer with Breathing Techniques and late-game Slayer Marks that push stats beyond normal caps
• ⚔️ Playing as a Demon with high HP and fast regeneration - but burning in sunlight unless protected by the Kamado Clan bloodline or protective items
• 💎 Collecting Sun Essence - the premium currency that grants Demons sun immunity and unlocks Sun Breathing for all races
• 🗺️ Hunting specific NPCs across the open world to unlock all six Breathing Styles: Water, Thunder, Wind, Insect, Flame, and Beast
• 🏆 Competing in PvP zones where race abilities and build quality directly determine outcomes
• 🎭 Re-rolling your Clan, Breathing Style, and Race to optimize your character without starting over

The Family and Clan system assigns each character a lineage on creation - most are cosmetic, but the Kamado Clan grants Demons sun immunity, a major advantage. Breathing Resets, Race Resets, and Family Rerolls are available in-game rewards that let players re-randomize build choices without starting a new character, making them highly sought-after each update.

Onikami Legacy competes directly with Project Slayers and Demonfall as a serious Demon Slayer RPG on Roblox, distinguished by its three-year consistent update record and deep lore integration.
