You can try this. Modify the "C" and "M"

this is really close. use lowercase. sure you'd have to modify esp the E

I doubt that it's a font. But East West looks really close

it looks just like "IMPACT" actually. that font is already on your computer if you have windows.

one punch man's font is rogue sans medium, just slightly squashed. Tried this in adobe illustrator and it matches perfectly.
