Its decent for a 1st chap, but the comedy is really flat and it trys way to hard to copy Im a spider, so what. Feels like a copy of Kumo eating the corrision larva/worm and picking the cute small form, but there it made more sense and was better developed.
Here it was picked, cuz of the voice and it feels extremely rushed. Gained like 30 levels in 5 pages and the form thats "supposed to be weak" onehit kills all basic monster in the forest. Also the art is waaaay to dark, messy and zoomed in for a combat oriented manga. Half the time you had 0 clue what even happened.
