Zongman: Beginning with the Killer Queen

Thank you for your invitation, I am in Fuyuki, I have just become a stand-in messenger, currently working in a convenience store in the business district, I get off work at 8 o'clock at the latest every day and go home. I don't smoke, and I drink only lightly. Get eight hours of sleep every day. My colleagues say I am normal.
Roland, who traveled to 1994, did not have any lofty ideals or pursuits, and only wanted to live a peaceful life.
It wasn't until the Fourth Holy Grail War broke out, and seeing the perverted killers, magician killers, and priests who claimed to be artists frequently appearing in his life, Roland realized that he needed to take some necessary measures.
All in all, anyone who disturbs my peaceful life must die.
