The pinnacle of lightning spirits, the Spirit King. True to its name — the Lightning Wolf (雷狼, Thunder Wolf) — it appears in the form of a giant wolf with lightning continuously discharging from its entire body. The most aggressive and battle-oriented of the four Spirit Kings, it instinctively respects the strong and despises the weak. Its howl is heard as thunder anywhere in the world.
Origin
Competing theories hold that it is the power of the Norse thunder god Thor dwelling in nature, or that it is the will of the storm god Indra from Hindu mythology spiritualized.
Features
- Absolute authority governing all lightning and electricity in the world
- Giant lightning wolf form — a single howl summons a continental-scale storm
- Near-instantaneous movement to anywhere in the world at lightning speed
- Grants the contractor 'Lightning's Protection' — near-light-speed reaction time and lightning immunity
Usage
Immediate reversal of battle situations. Records document the complete annihilation of the enemy's iron cavalry unit on the night Lightning Wolf howled.
Weakness
Pride that is strongest among the four Spirit Kings — completely ignores contract requests from beings weaker than itself. Poor compatibility with the Water Spirit King.
