It establishes the story with the protagonist Imako on her roller coaster adventure. Which leads to happiness and fulfillment through each scenes. The art; mainly the animation itself was not impressive, being aired in 2014 it could have had been a better quality of animation. The sound was not balanced (irregularities in volume) and had some rendering issues and had sounds that doesn't match the scene. The designs of the characters were odd (pointy, shaped characteristics) but cute at the same time. Overall its great it had that sense of story which revolves around the protagonist with an actual plot but did not suffice thestory itself and were quite confusing.
