He is seen having a thick, brown moustache and a brown beard. He also wears a spectacles which have a lens on one side. He is also seen wearing a suit with a pale green tie during his meeting with Seitenshi.
Sogen is seen to be a very serious man with firm beliefs. He is very direct and gets to the point of a conversation very quickly, such as telling Seitenshi his desire to unite all five areas of Tokyo. According to Rentaro, Sogen is a very dangerous man, one whom he labels as a dictator, and compares him to Sapporo, Sendai and Hakata. Sogen aims in making Japan the first country to recover from the impending Gastrea extinction, and in order to reach his self-proclaimed "vision", he is willing to use violence to get what he wants, with no regard for the lives of others. He aims to achieve his goals by means of force, stating that those who have power have to take part in his plan, declaring his will is the will of all Japan, such as it is his own.
Saitake arranged several meetings with Seitenshi, in which they would discuss various topics. At their first meeting, Saitake revealed his disappointment at Rentaro destroying the Ladder of Heaven to defeat the Stage V Gastrea Scorpion. He went on further to reveal that it was to be transferred to the surface of the moon to destroy Gastrea, although as Rentaro pointed out it wasn't the only thing he would target, as other countries were also on Saitake's list. Saitake accepted this, stating that after the Gastrea were exterminated, it was the strongest country that would come out as the new world leader, and he wished it to be Japan. He self imposes his own will as Japan's will, claiming that Japan wished it as so.
