# Chat Reaction-Sticker Cartooning (LINE)

> Cartoon character art made to be sent in chat: one figure performing one reaction, such as thanks, sulking, panic or a greeting, cut out on a transparent ground and sold in sets of a recurring cast. Where kawaii soothes, these sets stage exaggerated, comic emotions, often with a few lettered words, and must read at thumbnail size. It descends from manga cartooning and borrows kawaii roundness only as a base that the reactions then break; the emoji influence is the shared job of a pictorial reply, not a shared look.

## How it works

- Make each sticker a complete conversational reply: one character, one reaction, readable at a glance.
- Isolate the figure on a transparent ground with a clean outline and a small margin, so it can sit on any chat background.
- Frame close and compact; crop or squash tall bodies so the face and gesture survive at thumbnail size.
- Reuse one recognisable cast across a set, varying pose and expression widely, from affection to embarrassment to rage.
- Exaggerate faces and bodies with comic devices (sweat drops, tears, shaking lines), letting embarrassment or anger break the calm of a cute base; any lettering is a short phrase, and many stickers carry none.
