Saitama has a kid come to his door one day and just walks in and gives him a piece of paper and just sits down and watch tv. As he reads the paper he realizes he has to take care of this kid for who knows how long. He can't be defeated but will this be too much for Saitama? (I don't own One punch man or the cover picture I own only my oc)

Tatsumaki the Rank 2 S class hero, also known as the Tornado of Terror has never been the easiest person to interact with. Tatsumaki looks down on everyone around her due to her powerful Esper abilities. This has led to her having a rather small social circle that doesn't really include anyone she would consider a friend. So how in the world does she have a boyfriend?! Daigo Amari is a 25 year old man who lives a rather normal life, aside from the fact that he is the secret boyfriend of the Tornado of Terror! Daigo was born with powers like Tatsumaki and her younger sister Fubuki, but instead of destructive powers he has the power to heal any wounds with the touch of his hand! The small handful of people that know about their relationship question why Daigo would put up with Tatsumaki at all. All the Tornado of Terror seems to do is belittle and tell Daigo how pathetic he is, there doesn't seem to be any love for him in her heart. Daigo of course shoots down these claims about Tatsumaki because he gets to see a side of her that no one else gets to see. One Punch Man belongs to One and Yusuke Murata, I own my OCs.

Don't ya want Saitama to get more popular and get more recognized by the public? Also becoming a Class S Hero along with Genos? Well you have came to the right place. In this, you can read the Story of One Punch Man but Saitama is Class S. ( The parts are mostly canon, but i added a good amount of non-canon parts to the story too. )

In this story we see our bald hero Saitama become a symbol of strength and peace as he takes on the strongest enemies the earth has seen. This all started when he was walking back home and out of nowhere he sees a young girl with green hair fly towards one of the buildings, as she's about to get killed by the monster Saitama sends a normal punch and instantly kills it. As she falls accepting the fact that she's going to die Saitama saves her and carries her to his house to help her out. Find out what happens... (Some spoilers from the webcomic)

Holy god I have horrible story descriptions forgive me Saitama and Tatsumaki: two completely different people, who both have odd lifestyles. A guarded lifestyle, against a carefree one. Neither of them really know why they still hangout, but they do. And yet, both of them harbor their own issues. Tornado with her past and present relationships, and Saitama with his strength and emotions. Maybe, if the situation is right, it can be fixed. With a mixture of a shiny bald head, shiny green hair, accompanied by a dash of a strict cyborg, a younger sibling, and a whole ton of angry monsters, maybe they can get along after all.
