Yuuki Terumi is the true primary antagonist of Blazblue series and a former member of the Six Heroes, as well as the creator of the Azure Grimoire. He is also the founder of both the Novus Orbis Librarium and Sector Seven, often manipulating both sides to reach his goals. He became a playable character in Chrono Phantasma.

Cruel, sadistic, selfish, and insane beyond measure, Terumi delights in the suffering of others, both physically and mentally, and relished pure chaos. He would provoke and manipulate others for his own amusement, and would ruthlessly torture anyone who irritated him or got in his way. Unsurprisingly, this has earned him the contempt of almost every character in the BlazBlue universe, most notably Ragna, Kokonoe, and Nine. However, he is prone to breakdowns when things don't go his way.

Terumi is the catalyst for most of the events happening and a reason for almost every character's hatred: he turned Arakune to his current form, betrayed his old comrades, killed the sister taking care of Ragna and co., kidnapped Saya, hurt Tsubaki in more ways than one, and so on. The only people he is on "good terms" with are Relius and his vessel, Hazama. Even Izanami, who is supposed to be his boss, is willing to give his head to Ragna in order to cooperate with him.

The reason Terumi is extremely strong is because he feeds upon everyone's hatred: the more people hate him, the stronger he gets. Because the Master Unit acknowledges him as an evil entity, he keeps getting stronger. However, Ragna uses this against him in their final battle as he makes Master Unit acknowledge him as the hero he used to be - a hero everyone loves and respects, and who is not hated by anyone due to the fact he was one of the saviors of the world, which in turn takes over more than half of Terumi's power away.
