Rokushakudama Nenji Nenji looks like a tough guy on the outside, but on the inside he carries a very gentle and caring heart. Nenji devotes himself to the unique craft of making "hanabi", or in other words; fireworks. Some time ago Nenji lost his navi Nenjiro ("Son of Nenji") in a tragic accident, when a firework launcher went out of control. Coincidently, Napalmman hid himself in Nenji's now empty PET, too damaged to move further due to a run in with the Net Police. Without even knowing who he was, Nenji took responsibility for Napalmman and nursed him back to health. The end result of his actions formed a bond of friendship and trust, that convinced Napalmman to leave behind his former corrupt operator, and start a new life by Nenji's side.

Nenji is an awesome character that I enjoy very much. His personality is unlike what we've really seen before.
