But after witnessing every flock to Saiki despite him making is legendary face, Aren decided to try his best to befriend Saiki as well. Despite his violent nature as a delinquent, Aren has a keen sense of friendship, loyalty, as well as the will to protect the weak. Aren, with the strong physical fortitude he gained from being a delinquent, has protected many of his fellow classmates from the local bullies. His name is an anagram of "clairvoyance."
