Tōsan Getsueikirite

Tōsan Getsueikirite (月影切り手父さん, Getsueikirite Tousan) is the esteemed Lieutenant of the Eleventh Division, former Third Seat of the Sixth Division, and the father of Matthew and Sanji Getsueikirite. Despite being a Vice-Captain, he is one of the few members of the Gotei 13, that isn't a captain, to have Bankai. This is because he is already captain level, but was not chosen as his division's captain due to not being a Kenpachi. His sons are also unaware he is a member of Soul Society's military at the moment, as they believe he is a Human like they are and they also believe him to be dead, due to him never showing up in their lives after their births.

Appearance
Tōsan is a tall man with long, wavy, redish-brown hair and ruby red eyes. He does not wear traditional Shinigami garb, instead he wears an outfit reminiscent of Ryan's; a black overcoat with a high collar, black shirt, and black pants. He also wears black arm guards, two blue belts around his waist, and gray gloves on his hands. He carries his zanpakuto in the traditional manner; on his right hip, in it's sheathe.

Personality
Tōsan is a very noble and respected person in Soul Society. Despite being a Shinigami, he is very religious, believing that no structured government or army can be run without the help of God Himself. He is a patriot, believing that with the right guidance, Soul Society is the greatest society to have ever had appeared. Tōsan is also a very smart man, being well versed in military and political strategy as well as knowing how to use them to gain the upper hand in almost any situation. He seems to be very kind hearted, a trait not often observed in the Eleventh Division.

He is very loyal to his captain, and obeys orders without hesitation. He will, however, abandon his orders if they involve killing the innocent, or bringing harm to a child.

Background
Several decades before the start of Bleach - Generation III, he was sent on a mission for the Sixth Division in the Human World. While there, he fell in love with a human woman and married her in secret. She had Sanji and Matthew, but soon after, Soul Society demanded he return from his occupation in the Human world, so he told his wife never to reveal to their sons who he was and left his family behind in the world of the living.

Several years later, he snuck himself back into the Human world to visit his family but was shocked to notice a third boy among them, bearing little to no resemblance to him or his sons. His wife explains that she too doesn't know where the third boy, later revealed to be Ryan, came from, stating that he just 'appeared' shortly after Matthew's birth. She also says that Matthew and Ryan get along surprisingly well, but she doesn't know what to do with the strange boy. Tōsan was deeply troubled by this new information, and was further troubled when he realized that Ryan and Matthew were giving off the exact same reiatsu. He told his wife that for the time being, she had best take care of the new boy to see how things play out before leaving for Soul Society again.

Powers & Abilities
Master Strategist & Tactician: With his years of experience as a warrior, Tōsan is a very intelligent man. He is capable of quickly adjusting to new developments and making quick decisions accordingly. He has great tactical acumen, as shown from his preparations for the battle against a rouge Ryan Getsueikirite. As noted by the Eleventh Division's Captain, Tōsan is very cunning, setting up a trap to kill his enemies while they are focused on a distraction created by Tōsan himself in advance. His skill at battle tactics is undeniable, as a Vice-Captain he commonly sends the seated officers of his division out to engage in battle for his captain, be it to relatively small or large number of threats.

Master Swordsmanship Specialist: Tōsan is a highly proficient combatant. In combat, he doesn't seem the least bit taken back by the abilities of his opponent, even when they seemingly have an advantage. He fights with seemingly no effort behind his attacks. His ability to wield his combat skills was evident even when he was a Third Seat in the Sixth Division. He is commonly seen using his Zanpakutō's special ability, allowing him to be quite deadly at a distance, which is capable of killing multiple targets in one shot. He has shown the ability to use extreme speed mixed with a calm composure and precise attacks.

Flash Steps Expert: Tōsan was fast enough to sneak up behind his son, Matthew, before he realized it, demonstrating his skill with Shunpō.

High Spiritual Pressure: Being a lieutenant, it can be assumed that Tōsan has a large amount of reiatsu. When his reiatsu is being released, it causes the ground to tremble slightly.

Zanpakutō
Miezarute (見えざる手, Invisible Hand) is Tōsan's zanpakuto. It takes the form of a nodaichi with a silver metal cross guard and a long, blue hilt with a red jewel on the pommel.
