The character tags under `aoi_hada_no_ten'in_to_shiawasena_tomodachi` have a typo "shiwasena":
`ari_naka_(aoi_hada_no_ten'in_to_shiwasena_tomodachi)` -> `ari_naka_(aoi_hada_no_ten'in_to_shiawasena_tomodachi)`
`koike_(aoi_hada_no_ten'in_to_shiwasena_tomodachi)` -> `koike_(aoi_hada_no_ten'in_to_shiawasena_tomodachi)`
`kakeyama_(aoi_hada_no_ten'in_to_shiawasena_tomodachi)` is correct.
It also appears this copyright has been renamed by the artist, but I do not know how to handle that change if it is necessary to make.
