The Demon King Succession Tournament

A hostile trial called by Clayman to accuse Rimuru of breaking the Demon Lord rules.

The Demon King Succession Tournament

The Demon Lord Banquet (Walpurgis) is a hostile gathering called by Clayman to accuse Rimuru Tempest of violating the 'Three Demon Lord Rules', not to judge his qualification or settle the Orc Lord and Charybdis conflicts. Held at the Demon Lord's Castle in the Milishion region, the event is a trial of power where several Demon Lords initially oppose Rimuru, and Milim Nava is merely pretending to be under Clayman's control as part of her own plan.

Lore & Background

During the proceedings, the gathering is hostile, with several Demon Lords initially opposing Rimuru. Alliances are tested through proxy battles and strategic displays, and the atmosphere is thick with tension. Milim Nava is not genuinely manipulated; she is pretending to be under Clayman's control as part of her own plan. Ultimately, the banquet does not create a council-like structure; Rimuru is recognized as a Demon Lord, Clayman is executed, and the Octagram is formed, but the political structure remains a hierarchy of Demon Lords.

In Their Own Story

The air in Zegion hummed with the static of raw mana, a palpable pressure that made the stone floor tremble. Rimuru stood amidst the gathered lords, his form shifting subtly between slime and human guise as he surveyed the arena. To his left, Milim cracked her knuckles, a playful grin masking the terrifying power she held in reserve; to his right, the stoic gaze of the other great lords weighed heavily on the silence. It was not a battle for survival they sought today, but a declaration of intent. As the first challenge was issued, the ground shook, not from an explosion, but from the sheer weight of destiny shifting toward a new era where monsters and humans might finally walk side by side.

Reader's Guide

The arc begins with the formal invitation to the Six Great Demon Lords to convene in the capital city of Zegion. The premise is straightforward: determine who will lead the demonic race into the future, but the execution involves complex political maneuvering rather than simple slaughter. Key turning points include Milim's initial reluctance and eventual acceptance of Rimuru's influence, as well as the strategic interventions by other Demon Lords who recognize the futility of opposing Tempest's growing power. The conflict shifts from physical combat to a contest of ideologies, where Rimuru's ability to unite diverse races becomes his greatest weapon. This arc advances Rimuru's growth by forcing him to step out of the role of a local ruler and into the spotlight as a global leader. It solidifies the transition of Tempest from a regional nation-state to a central pillar in the world's balance, effectively ending the era of isolated Demon Lord fiefdoms.
