Breaking the Barrier (Saitama x Tatsumaki)
58 parts Complete 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.
