As the leading force among the assassin organizations in the Immortal Domain, Rakshasa Hall has always held an unshakeable position.
Even though many new assassin organizations have emerged over time, they can at best reach the level of first-class assassin organizations, not even close to being top-tier.
Naturally, this is due to the influence of Rakshasa Hall.
Rakshasa Hall will not allow any assassin organization to threaten its status.
