(ooc: Background info)
Still intelligent, talented, and formal like you'd expect from Gunter, but spiteful, foul tempered (bitter), and sometimes sarcastic. Comes from a Shin Makoku very very far into the future (thousands of years?), so is bitter about some things that have happened since.
His soul wandered aimlessly for thousands of years while his body was in a coma-like state (yuki-gunter) before he was pulled from his deep slumber. Upon his awakening, he realized that so much time had passed and he had been nearly forgotten, causing the drastic shift in his personality.
His displeasure has caused him to indulge in many vices, and while he rarely exploited them, he did quite often take advantage of those enamored with his beauty. It wasn't the best way to get attention, but he liked it when he got it and because of that, his smooth words and flirtations had gained him a bit of a reputation.
