And this nutcase would be Murasaki Ryo's lovestruck
husband: Shirou Ryo.
He's the type of guy who loves without limits, loves life, and is happy-go-lucky just like his oldest daughter. He's so
stupidly intensely devoted to Murasaki that he convinced her to marry him by agreeing to any conditions she listed, one being that she keep her last name and her job. Shirou took that a step further, and replaced his own last name, Aoi, with Murasaki's once they were married, as proof that he is her's, now and forever.
(insert 'awwww's here)
Shirou is kinda the stay-at-home-Mom of the relationship, except that he works. He both ownes and works behind the counter of a convenience store, and works hard and long hours because he's working to support two mercenaries, his wife and his oldest daughter. Although Ruru doesn't really count as a mercenary, since she's just traveling with her Mom to get information. Shirou also cooks, cleans, and helps Ruru with her homework. Although sometimes he has Ruru help out with the chores.
He absolutely loves this life he and Murasaki have built for themselves, and it glad that she agreed to take him. They both worked for Calvin Darkart as part of The Syndicate, though Murasaki had been a much higher ranking member than he had, and so they knew each other for many years. Shirou was never really evil, and could tell that Murasaki wasn't either. Which is probably why he fell in love with her, and hasn't looked back since.
Shirou is an older bundle of limitless energy now, but he's also incredibly romantic and charming. And tends to go a bit overboard when Murasaki comes home after long trips (which Ruru doesn't always accompany her on since she has school), and at times blends every cliche thing 'the book' has to offer. He is dedicated, loyal, selfless, and intelligent, and is very generous with people. Almost like he's trying to make up for all the lives he has taken, though at the same time he accepts Murasaki's job. Unconditional love.
Like a puppy.
A great, big, man-puppy, and he really is. As well as a great big teddy bear. However, if you mess with his family you will live to regret it, if you survive. He has not lost his touch in the art of fighting, and takes over training Ruru while Murasaki is gone (if you count randomly attacking and throwing tables and such at her 'training'). He will fight for his family to the death, and would gladly surrender his life to protect them. He would also sacrifice himself if Calvin returned for Murasaki, to keep him away and keep his love's freedom.
So, you want 'im?
His face claim is Tsubasa Amaha.
