Kenka Dokugaku

Both are animes that revolve around fighting, and also both have mcs that do not know how to fight. The biggest difference is that the Bucchigiri MC is an insufferable simp that will do anything for a girl that doesn't care even the slightest bit for him, while the Viral Hit MC is a loser that gradually grows and tries to overcome his plight. Be ready to see the MCs take a lot of hard losses though. Hard stuff to watch, but its worth it in the end...sort of. 

They are both originally manhwas and webtoons. They both have a similar art style and plot. The main character is a student in both shows and is generally seen as weak, out of shape, and unable to defend themselves. Then they both go through a change that sees them rise in popularity and become a better version of themselves. Both are all right shows. Sometimes the plot gets a little ridiculous and the bullying is kinda forced but I think they are both worth a watch. I give Lookism a 6 and Viral Hit a 5. 

Might be a bit of a reach, but i feel like they both have kinda similiar humor. I kept being reminded of grand blue when i watch viral hit. They both fun watch and kept making me lol-ed Viral hit is obviously more violent than grand blue. 

While our main characters don't look all that similar other than the black hair, but I feel their circumstance is and that they both start off as weak. basically 'zero to hero' story progression both mcs: have someone teaching them (even if one of them is an online sensei) wish to become stronger are learning how to fight/defend start off bullied by others battle difficulty with opponents increases
