Tamayo Kizuki

Tamayo is 12 years old and is a friend and classmate of Misaki. She nicknames Misaki Misakichi and is rather eccentric. One of her favorite activities is practicing her martial arts techniques on her unwilling friend Kotaro. She always loudly cheers for Misaki at Angelic Layer matches and defends her against those who question her ability. It is later revealed that Tamayo has always held intimate feelings for Kotaro which may be one reason why she always added chan which Kotaro complains is only meant for girls and little kids to the end of his name instead of kun despite him being in middle school. She offers to be Misakis second in her national game match against the Angelic Layer Companys angel due to Hatoko becoming ill before Misaki accepts Ohjiros offer to be her second. Source: Wikipedia
