>>3 Most people these days include a "Saitama doesn't count" rule in threads like this as he's basically the Chuck Norris of anime, so this thread may need amended. Aside from Saitama, the strongest is definitely either Yuu from Charlotte (at his peak), or Ains Ooal Gains (a.k.a. Momonga) from Overlord. Though Blank from No Game No Life easily beats both of them if the siblings are together.
