Souichi Kusakabe (草壁 蒼一 Kusakabe Souichi) is a sub character in 11eyes and 11eyes: Resona Forma.


According to Misuzu, he never loved her and was indifferent to her mother, a trait that made Misuzu want to seize the Kusakabe Five Treasures all by herself, only to get his attention. In Misuzu Route of Resona Forma, it is revealed that Souichi actually cared for his family. He approved of Misuzu's return and had even built a house some time in the past so that Misuzu could return whenever she felt like. During her stay, he seems to be somehow protective of her, trying to defeat the invading demon sword all by himself despite his condition.


Souichi is Misuzu Kusakabe's father and teacher. He is the current head of the Kusakabe clan and was also the owner of Doujigiri Yasutsuna; the Kusakabe refers to him as Noble House Lord (御館様 Oyakata-sama). In the battle for the final sword of the five treasures, Doujigiri, Misuzu amputated his right arm, rendering him unable to wield a sword. He seems to have been given a prosthetic arm later, however, and continued his role as the head of the clan.


When Misuzu returned to the Kusakabe village, an audience with Souichi, as well as other representatives was summoned. While others foul-mounted Misuzu without any reservations, Souichi simply listened. When a villager proposed expulsion, Souichi simply laughed, calling Misuzu's story of having defeated Misao Kusakabe, the strongest Onmyouji ever existed, and then returning was quite amusing. When the meeting ended, he approved of Misuzu's return and gave her a place to stay, but rejected her as his daughter.

In November, when the a vengeful spirit of the Azo Clan, who came to massacre the Kusakabe, was on the run, Souichi wielded Doujigiri once again to pursuit it. Misuzu and Kakeru Satsuki, however, stopped him and volunteered to do it in his stead. He disagreed at first, but consequentially yield to her request when she summoned the Kogarasumaru Amakuni. After Misuzu had defeated the demon sword, with some help from, Kakeru, Souichi met her again, saying that both of them did well.

In the future, Souichi and Misuzu worked together to mentor Kakeru about the way of an Onmyouji. He also approved of their marriage, telling Kakeru that he would put his daughter under his care.
