Tokiya loved Aki lots and when Akis soul wore away Tokiya confined himself because he couldn't live without a world without Aki.
Because Tokiya could not keep living in a world without Aki, he made a contract with Hiwako and became an Asura Cryin' after stealing Hagane. He intends to use the Hagane's time-space manipulation powers to create a 3rd World and start everything all over again.
Using Hagane's power, Tokiya gains Hisui, Bismuth, Rhodonite. Using all 4 Asura Machina he gained, he make Central Vortex that goes out of control to start the destruction of the Second World. After gate to the Third World opens, he goes into the Third World with Hiwako.
After realizing that Third World wasn't the world he imagined, he seeked to take Igniter from Tomoharu's party in order to create the perfect world he dreams of. He clashes against Tomoharu's party to create that perfect world even if it means to destroy every world including the First World, Second World, and newly created Third World to create that perfect world.
