After losing his home in the Ikaruga Civil War and his master Tenjō at the hands of Jin Kisaragi, Bang and his followers began living in Kagutsuchi waiting for the right moment to strike back at Jin and the NOL. There, he declares himself a hero of love and justice, and dedicates himself to exterminating evil and overturning injustice wherever he goes. Over time, Tenjo's teaching prevailed over him, and Bang develops a strict 'no-kill' policy, which means he would never stoop so low as to kill his enemies, even Jin, despite how much he hates him. However, he states in his story line that upon meeting Hazama that he must be killed, perhaps meaning that his 'no-kill' policy does not extend to the truly evil.

He has a romantic fascination with Litchi, always willing to go charging in headlong if he sees someone making her upset. He is overzealous in every way, subtlety not usually at the forefront of his mind. However, his fiery spirit and will have earned him the respect of a few characters, most notably Hakumen. His first and foremost duty is to protect the citizens of Ikaruga, which was the reason why he also wants Ragna's bounty: to rebuild the glory of Ikaruga.

In Continuum Shift, he goes on a mission to find his Master's Son, although as his story revealed, his true ending in Calamity Trigger did occur and he survived the beating he got from Hakumen rather than dying (his death was a story made up by Taokaka). There is an inactive, unknown Nox Nyctores within his possession. This is earlier stated by Rachel in Calamity Trigger. This Nox Nyctores turns out to be Phoenix: Rettenjō, the Nox Nyctores with the power to sever connections with The Boundary. Platinum the Trinity informs Bang of this, but vanishes before he could gather further information about it. Although it takes place in non-canon, Ragna states in the last episode of "Teach Me, Miss Litchi! <Reloaded>" that it has the power to destroy other Nox Nyctores.

Platinum the Trinity also revealed to him that his true enemy wasn't Jin, but the system within NOL. After an encounter with Hazama, Bang decided to travel to Ikaruga to uncover further mysteries about its destruction and NOL's involvement in it.
