Hayakawa

+10 Posture, +30 Soul

1. Slightly reduces the requirements of all contracts

Hayakawa is arguably the best clan in the game. The contract requirement reduction benefits literally every build—whether you're running Ghost, Snake, or any other devil contract, you'll hit your power spikes faster. On top of that, +30 Soul and +10 Posture are excellent stat bonuses that make your character noticeably tankier and more resource-efficient.
