this clan is the family of the great hoshankage *Nitatsu. ichiban meaning first. The ichiban are the descendants and reletives of THAT MAN who founded the village. this family runs the geothermal energy plant and provides power for the whole village. they live in a manor ,next to the plant,inside the volcano. they aren't very rich but are considered Nobles because of their lineage and importance to the village. the ichiban have a multi stage kekkei genkai. some members gain the ability to generate intense heat and are immune to burns. however nitatsu and some of his children have these abilities and can even create lava/magma from their very bodies. Some believe Nitatsu has even more powers than that.

*remember nitatsu is just his ninja title (two dragons), not his birth name
* there are other clans but these 9 are the most significant.
