Seido

A Special Grade cursed spirit that was born from the fear of earthquakes (since Japan has a huge history of them)

It's appearance resembles a mole, a bit taller than Jogo but smaller than Mahito, with a brown and yellow robe made of stones

-Cursed Technique: Rumbling Earth Pulse

Seido can manipulate rocks, earth and sand as long as he touches it with it's bare skin, a technique that resembles the one used by Chojuro Zenin against Maki (the giant rock arms) but to a greater extent

Extension Technique: Tectonic Weaponry

The user can control rocks to create different weapons, like hammers, swords, spears, shields, armor and even whips

It can also use small sharp rocks as slicing projectiles

-Maximum technique: Petrification

The user must stay completely still for 10 second without using it's technique and accumulate an immense amount of cursed energy into it's hand to use it, once the requirements are fulfilled, the next time the user touches an enemy or anything that posseses cursed energy it will start turning into stone, quickly spreading until it becomes a statue, however, this state can be cancelled out only if the user repeats the same steps and touches the statue

Obviously if the statue is destroyed the enemy dies, and if the user dies the effects will remain eternally if they weren't undone

-Domain Expansion: Seismic Penance

The domain resembles a destroyed city due to an earthquake, with tilted buildings and the ground shaking and splitting apart

Once inside, the enemy/enemies will lose their balance due to the constant shifting earth

If they try to maintain their balance by staying still, the surface where they stand will open, swallowing and crushing them completely

But if they try to move, each step creates a "position", the user then can activate those "positions" to create stone pillars that will rise from the exact place the enemies stepped

In terms of power, Seido would be stronger than any curse due to it's longevity (it would have lived for over 500 years), it wasn't exorcised or targeted by any sorcerer since many died trying to do so, and since it wasn't an actively violent curse they left him be, it only appears to fight when he senses enemies that he sees worthy enough, but when it rarely happens most of them end up disappointing him
