The rules for the KASSEN match are as follows:

1. Match Format and Victory Conditions: Team Composition: A 3vs3 team battle with a total of 6 participants. Set Score: Matches are played in a best-of-three format. Final Victory Condition (Important): It is not simply about destroying the castle. You must capture the opponent's final main castle, the 'Tenshukaku'. You win the round completely by striking and toppling the 'Taisho-otoshi', a multi-colored disc that appears after unlocking the Tenshukaku's final seal.

2. Battlefield Structure and Capture Order: To win, the game must follow these clear step-by-step rules (Flow): [Defeat Ushi-oni (Neutral Mob)] ➔ [Capture Yagura (Mini Base)] ➔ [Taisho-otoshi Appears] ➔ [Final Fall of Tenshukaku] Three Lanes: The battlefield is divided into three attack routes: Left, Center (Mid), and Right. Ushi-oni Hunting: You must first defeat the 'Ushi-oni', giant monsters placed on the battlefield. Sub-Tower 'Yagura' Capture: After taking down an Ushi-oni and advancing, you must capture at least one 'Yagura', a mini-base on the line, to deactivate the shield on the enemy's main castle.

3. Class and Weapon Creative System One Weapon (Single Slot) Limit: A user can only equip one weapon during the game. User Custom Design: The appearance and gimmicks of weapons can be designed by the user in a 'Hybrid (Multi-tool)' fashion. (e.g., Iroha's musical instrument-type dual blades, etc.) No Pay to Win: Paid items to increase character stats are strictly prohibited. Only 'Avatar appearances and skins' that do not affect balance can be customized, prioritizing the player's skill and planning.

4. Gauge and Awakening System Combat and Farming: The Ultimate gauge fills up when you hit enemy players or hunt neutral mobs. Awakening (Deification): When the gauge reaches 100%, the character enters a powerful area-of-effect skill and buffed state (Awakening) accompanied by a unique mythological presentation.
