Insect Storage Seal

This is where Bobu Nomi keeps most of his bugs. From here they are linked to his Area Draining Seal (of which he has several variants, some for long range, medium range, and short range). From here he can get gigantic kidaichu summons by feeding them tons of chakra, and safely use them for his Area Draining Seal. This insect storage seal can be freely opened and closed, similar to a pouch, and is advantageous in that it keeps his kikaichu and kidaichu safe when not in use. This also prevents his insects from easily being killed off via a large scale jutsu, and ensures that he always has backup bugs and sufficient bugs to fuel his area draining seals.

Bobu Nomi has a vast number of insects stored, courtesy of him providing additional platforms to reproduce and grow. It can be said that the storage seal passively uses the Coccoon technique, but the numbers are so great that this does not have to be in play at all.

Regardless, this means that his Area Draining Seal is much more effective than most might make of it, as he has far more kikaichu and kidaichu supporting the draining process. He may freely allocate his insects at will and summons them. The storage seal also has the added effect of being a conducive breeding environment for these insects, extending their lifespans and generally maintaining the population of the insects within it. He can summon gigantic kidaichu from this (particularly the largest ones, which are at the size of a boss summon and literally eat chakra).
