Structure the review with an introduction, brief plot summary, character analysis, animation, music, and a conclusion. Mention the title's ambiguity and suggest verifying the correct name. Ensure the tone is helpful and informative, not misleading. Maybe add a rating based on the hypothetical elements. Check for any possible similar titles or if "DOSHICORU" is a typo for "Dosu-korobi Uta" or another phrase. Since I can't confirm, proceed with the given title.
