A proper picture of Blank just had to be made, and well, here he is.
Blank
Age: Unknown.
Height: 6"3
Weight: 345lbs
Blank is a Jiroo of an unusual color. Tested for an experiment at an early age, and then put away as to not raise suspicion. Since then, he has been brought up by low lives, and the twisted.
Growing up, he became self reliant, looking out for himself until finally being tracked down and used for military purposes. This has helped him become familiar with weaponry, which led to him having way too much fun. He has been charged for many illegal actions which have put him in jail countless times.
After while, he had become one of the top criminals for abandoning his post, and leaving the country. Soon he met a small Daimon by the name of Brokun, who not only joined forces with Blank, but also fixed the system so that all of Blank's criminal records were wiped so he could start things off clean..However, this didn't last for very long.

Irritable, a drunk, perverted, and violant. This Jiroo is a danger to those around him, and even himself. The only other living being who can rival this crazy behavior is Trigger, with which the two share a mutual dislike for one another.

Well that was a long description, I hope this doesn't bore any of you to death
