Weirs & Trin
Weirs and Trin are the protagonists of Tone Sphere. They meet when Weirs appears in a mirror in a lonely Trin's castle room, and leads her on an adventure.
Neuman calls himself the warden of cosmos, but Weirs and Trin consider him to be more of a garbageman, much to his annoyance. When they meet him, he entreats them to bring Damsel to him in order to save the malfunctioning Darksphere.
The source of a glitch spreading through Darksphere, Damsel was once close to the creator of the universe. She was left behind when she abandoned her creation.
Opto-sensei acts as a guide to Weirs and Trin as they explore the Tone Sphere universe. May or may not be the first beagle in space.
