This scene from episode 1 of Railgun shows Misaka Miko using her signature move called “Railgun”. The animation in this one scene rivals the entire season 2 of One Punch Man.
Funny that we bring that up because the same animators who were in charge of One Punch Man season 2 are the same people who animated Railgun. That team is called JC Staff.
Why does the animation look different you say? It all comes down to money. Maybe ONE didn’t have the budget for top quality animation to pay JC Staff. This is something to definitely discuss in the near future.
