A resident of Sumeru, Cyno is responsible for keeping scholars in check so as to not spread banned knowledge and academic corruption in the Akademiya. He takes his job seriously, with a overprotective tendency. As the General Mahamatra, Cyno leads the Matra and strikes fear into the hearts of researchers of the Sumeru Akademiya. In spite of this, Cyno has a fun side outside of his role in the Akademiya, as he has an affinity for Genius Invokation TCG and constantly cracks unfunny jokes.
