23 Blast is actually fictional. The plot and characters are made up to engage the audience and tell an interesting tale. It doesn't draw from real-life events or people.
One possible back story for an Eldrich Knight could be that they were once an ordinary knight in a small, war - torn kingdom. During a particularly fierce battle, they stumbled upon an ancient, arcane artifact. As they touched it, strange energies surged through them, awakening an inner power. This power was the start of their journey into the eldrich arts. They then sought out reclusive mages to learn more about this new - found power, gradually becoming an Eldrich Knight.
An Eldrich Knight could have a back story where they were an outcast from their tribe due to a strange mark they were born with. This mark was actually a sign of latent magical ability. They wandered the lands alone until they came across a ruined temple. Inside, they found ancient inscriptions that seemed to call out to them. Deciphering the inscriptions over time, they learned how to harness their magic in combat, thus becoming an Eldrich Knight.
In these stories, a typical element is the protagonist's struggle against the transformation at first. They might try to resist the dark influence that is causing it. The transformation also tends to be accompanied by strange phenomena like the sky turning an unnatural color or the ground shaking. Moreover, the transformed eldrich monster often has a hunger or drive that is not of this world, perhaps a craving for chaos or a need to spread the same transformation to others.
The characters included the male lead, Fang Changshan, and the female supporting character, You Meng.

"Experiment No., Night Roar Mecha."
"Hostless state."
"Do you want to bind it?"
"Yes." Fang Changshan made his choice without hesitation.
"Activating…"
In the next second, Fang Changshan's vision became abnormally tall, wide, and clear.
Endless power surged from the origin heart in his chest. As long as he wanted to, he could instantly move dozens of kilometers and blow up a planetary state monster!
I hope you will like this book.
I'm not sure specifically as there could be many 'blast graphic novels' with different stories. It might be about adventure, with characters going on exciting quests, facing challenges and using their unique abilities.
