The Uncanny Counter

Both are action oriented stories with a focus on friendship, loyalty and mastering the classical virtues (Prudence, Temperance, Fortitude, Justice). This mastery being expressed in martial prowess; allowing the main characters to transcend their psychological and social "prisons".
As for differences Fight is far more subdued; it takes longer to tease out it's themes; the supernatural isn't explicitly expressed; and humor more subdued. In the same vein vice and virtue in the characters is expressed in a more subdued manner in fight.

the bully in SB is also the bad guy in UC - Jung Won Chang
same trope where both the MC is being bullied then suddenly got stronger only difference is Uncanny Counter focuses more on killing the evil spirit and not as being bullied unlike Shark the Beginning both are great tho

– Both have spirits taking over human bodies.

– Both leads seek justice or revenge in the modern world.

– Characters struggle between who they were and who they are now.

– Their painful pasts drive their new missions.
