He is very polite and reliable. He is usually seen smiling & loves tea and teaches calligraphy. It was revealed that his mother died as a sacrifice to seal the onikirimaru, which Suguru still remembers.
Suguru seemingly betrays the guardians and Tamaki in season two, his reason for doing so as he stated was that he believed that Logos had the right idea when it came to what should be done with the Onikirimaru. Later it was revealed that he joined Logos so that he could get the five artifacts back, originally belonging to the Tamayori princess.
While snooping around Logos' hideout he encounters Vier a woman (later revealed to be a homunculus) who resembles mother and eventually comes to learn that she was created by Drei and fashioned in his mothers image.
