In the world of Chuushin, exist two master races, the otherworldly demons and the humans blessed with vitality. At the beginning of history humans respected the raw power of the demons and demons admired the innovation of human spirit. They learnt from each other, and propelled each other into a golden age of prosperity. It was nearly a millennium later that a young hanyou upset that he would not inherit his father's throne pitted the two races against each other through the shogun's favorite wife (not the demon's mother) who instead of bearing a human child, gave birth to a hanyou instead. With the seeds of mistrust throughly implanted into the head of the shogun he began systematically killing any demon that worked in the castle blaming them for his wife's infidelity and by proxy he killed his son.
In retaliation, the demons launched a attack on the shogun, and a series of epic battles broke out.

Between these two brother races, now filled with hatred and bitterness, miasma was born. Miasma caused both races to go insane with killing intent and this substance further fueled the war. However with the intervention of a human monk with the immunity of miasma they were able to free themselves and "cleanse" the miasma. Realizing the destruction the races had both caused they had begrudgingly formed an alliance to help fight the miasma and the creatures born from it's wickedness. Only through the teamwork of the demons who can accept the miasma in to their bodies and channel it with the help of a exorcist and the exorcist who can purify the miasma. After 3 generations many groups have tried and failed to become a top class cleansing organization. One group in particular gave birth to our story.

Baj: girl with power over talismans as you had previously stated. i have a weak raw spiritual power, but through the use of applying the work through the talismans (as a form of earth energy i'll explain later), i can create support talismans that would mainly be used for my familiar.
Habitat: small hut in the forest that looks sorcerer like (small, seclusive in a forest, etcc)

My familiar: a fire elemental baby tiger. fur pattern is the same, but colours differ: black as a base colour, with red strips, and a few white stripes. its fire elemental is shown at the paws, end of tail, ear tips, and along the back of its neck/back (following its spine), till midway down the back. this familiar is more for company in its baby form, though is crutial to the creation of the talismans, as there needs to be some way to "fire" the talismans (like clay, but no kiln, etcc) as the talismans will be made out of earthly elements hence why i vote being an earth elemental person, as well as living in the forest ^^~

Battle tactics:
during fights i funnel my spiritual energy into the talisman connected to my familiar, and use it's earth qualities (of growth, if you approve of it XD) to speed the growth of the cat into a more adult version (sorry its a semi-copy of uri from khr with the whole kangaryuu thing but i swear i didn't plan it out like that >.<)
of course this wouldn't last long as my powers are pretty weak, but it would last long enough for certain (smallish) fights for self protection.

Contributions to the group:
mainly a support character, making talismans that may work in similar fashions as with my own familiar, but of course being more specific to peoples scenarios, etcc

If you want more description on the details of such things, trust me, i've got it allll planned out in my mind XD
though i'll keep it to my character specifc, and of course avoid overpowered situation type things XD
