Would you prefer Simo be a normal guy?
Basically, every previous human fighter has had an exaggerated tragic backstory and/or enhanced superhuman abilities. Rasputin, Kintoki, and Nostradamus are probably gonna be the same. Would you prefer Simo be the one guy without them? Like what his intro says, he was just a normal guy who saw his homeland be invaded, then picked up his rifle and fought them back. Then in real life, he just retired and lived a normal life taking care of dogs. He has no superhuman eyesight or enhanced senses, he would just be a guy really good with a rifle and really good at stealth.
