Jin Arizuka

Sōsei Yoshino (芳乃 創世 Yoshino Sōsei), also known as Odin (オーディン Ōdin) is the main antagonist of Fortissimo//Akkord:Bsusvier. His role is extended in Fortissimo EXA//Akkord:Bsusvier.
==Appearance==
Sōsei has short brown hair with white bangs and red eyes. His build is one of the most muscular in the whole game, secondary only to Hagane Todoroki. He is said to be as young as Reiji's brother (if he had one), a side-effect of being a magus.
==Personality==
In his youth, he is said to have a very strong sense of justice and would stand up for his loved one. These aspects of his still have not changed in the present, since Ryūichi looks up to him because of them. However, the loss of his most loved one caused him to turn cold and brutal; despite this, Sōsei himself states that he is just the same as before. Although he does not particularly care if his own son dies participating in Ragnarök, he truly regrets the fact both him and Ichigo are dragged in his ceremony and wished that it could have been different. Nevertheless, his determination is powerful enough to help him overcome his reluctance and continue with Ragnarök.
==Synopsis==
Sōsei is Reiji's father and Ryūichi's foster father. He was the one who put an end to the war for O Parts years before the events of Fortissimo takes place. During this time, he was partner to Ichigo Sagara. However, the war ended with SAKURA, his wife's death and left him with nothing but emptiness. Determined to change reality, Sōsei created the battlefield of Ragnarök, a ceremony that would help him attain the ultimate magic to revive SAKURA.
Some time before Reiji's returned, Sōsei let Jin Arizuka know about Ragnarök and agreed to share the right to be the Game Master, since he did not want to show up by himself. He hid his presence in daylight and silently watched Ragnarök while Jin was in control. After Jin was killed, Sōsei personally supervised Eye Space like how it was meant to be. From that point onward, Eye Space did not occur randomly on a whim, but was triggered whenever the combatants were needing it to fight. Sōsei planned to watch the ceremony take place until there was only one survivor left, but when Reiji broke the rule of the ceremony by letting Momiji Satomura live after destroying her Magic, he showed himself to kill Momiji and remind Reiji of the rules. With Momiji's battle finished, Sōsei erased his
