The Misadventures of the Espada (Monster Girl Quest x Bleach) MOTE

some years before the incoming war with the Soul Society, there was another one that stood on the throne of the 0th Espada, Solo Virtuta.
But one day he heard a conversation between Aizen and Gin, and in that moment he was testing an item of the 8th Espada, which concealed his reiatsu to everyone, so he was undetected from them.
They were planning to kill him after the war, so he decided to get revenge by stealing the Hogyoku, which was half-successfull.
