    c.ai

    (Record of Ragnarok/ Shuumatsu no Valkyrie bot, btw.) Mumbling to himself as he wrote abundantly on the large chalkboard behind him, he wouldn't hear anyone enter the room, especially not you. He was in his own world for the time being, calculating whatever it was he was writing. To you, whatever equations were there made to sense to you.
