Overview

Jung Sookja's entire world is her grandson, Gwon Yonghee — so when he ends up in a coma after an attack tied to the Black Star Mob, and the people responsible walk free anyway, something in her breaks. Two men show up soon after with an offer: they'll train her to fight, and she can use that training to take down the mob herself. Granny follows an elderly woman with no combat background at all as she's rebuilt, piece by piece, into someone capable of actually doing that.

Written and drawn by Jaehoo, this webtoon takes a premise that could've stayed a gimmick — "grandma becomes an assassin" — and plays it with more sincerity and grounding than the logline suggests.

What it does well

The smartest choice Granny makes is refusing to let Sookja's age be the joke. She's not written as a spry action hero in disguise; she's genuinely an older woman starting from nothing, and the story takes the physical and mental toll of her training seriously. That groundedness makes her later competence feel earned rather than convenient — by the time she's capable of standing up to the mob's enforcers, you've watched the specific work that got her there.

The emotional throughline never gets lost in the action either. Everything Sookja does traces back to her grandson, and the story keeps returning to that bond rather than letting the revenge plot become an excuse for spectacle on its own. That keeps the stakes personal even as the scope widens into a full confrontation with organized crime. And because Granny tells a complete story, the arc from grieving grandmother to capable fighter actually gets to resolve, instead of stretching out indefinitely.

Where it falls short

The Black Star Mob itself is mostly drawn in standard villain terms — dangerous, cruel, and there to be dismantled, without much individual nuance among its members. Sookja's two mentors are useful narratively but don't get much development beyond their role as instructors; we learn what they teach her more than who they are. And as the story pushes into its bigger confrontations, some of the fights start to lean on more conventional action-genre beats than the careful, character-driven buildup of the earlier training chapters.

Verdict

Granny takes a premise that sounds like a punchline and turns it into a genuinely affecting revenge story, anchored by a lead the genre rarely centers. If you want a complete, emotionally grounded action series with a real hook, this is worth your time.
