It frequently damages machinery and equipment without any intent, making it troublesome to handle.

Thunderbird
IntermediateThunderbird — Intermediate Lightning Spirit
The intermediate rank of lightning spirits. Appears in the form of a giant bird that triggers lightning with every wing beat. Takes its name from the Thunderbird of Native American mythology, described as a being that appears with storms. Free and tough in personality, it demands strength from its contractors.

Thunder-Drake
GreaterThunder-Drake — Superior Lightning Spirit
The superior rank of lightning spirits. A dragon-form spirit draped in lightning, a mighty being on par with the Fire-Drake. Only fully materializes within lightning and storms, known for freely striking lightning while cruising between clouds. Its very roar is identical to thunder.

Storm Emperor
SupremeStorm Emperor — Supreme Lightning Spirit
The supreme rank of lightning spirits, positioned just below the Lightning Wolf Spirit King. Can electrify the entire atmosphere. Appears in a form intermediate between humanoid and dragon, its entire body composed of lightning. Around it, compasses stop working and all magical devices malfunction.

Lightning Wolf
Spirit KingLightning Wolf (雷狼) — Lightning Spirit King
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.
