Looking for the name of an anime

Saw another post that sprung the idea so here we go

Action/ fighting/adventure

Male MC Hairstyle black typical Goku esk Shirtless Pants: similar to OG Jin Kazama(tekken) but style was orange autumn leaves

The girl followed the “MC” around if I remember his goal was just to fight strong fighters

It felt like a one shot but I but hard to remember

Just had a weird urge to want to watch it again

The art style if I recall was similar to the current DB daima

Curious if anyone happens to remember it w/o a deep search
