Good! Just like most other bugs, the can release pheromones too, which you will learn to track and recognise.
The benefits of Fireflies is that they have several utilities that you can capitalise on. They can create vibrations with their wings, for wind jutsu, channel chakra through their tail for lightning, they can track targets with their eyes, they can hum as a medium for your sound ninjutsu, as lastly, their tail glow can be used as a medium for visual genjutsu.
Fireflies grow up in a variety of climates, however they are quite resilient to water. (OOC I need to resubmit the contract with updates. Ill be adding in water resistance to it, up to A rank.)
Now, do you want a tattoo for quick summon, or do you want to leave that for now?
I will also need you to sign this contract.
As Zatanna taps her summoning tattoo, a large firefly, roughly 2 meters in size appears buzzing infront of her carrying a scroll on its back. Unkown to the new initiate, she begins humming with her mouth and points towards the young student. With a final nod, he releases the scroll, as it falls towards her. As she rolls it towards Howlett, she looks up and smiles; Dont worry, youll learn how to speak their language as well.
