Guitar Samurai the Man vs. Guitar Samurai the Monster as this tag
Linked entities: /tag/ギター侍
Although the character in the anime (https://myanimelist.net/anime/8365/Crayon_Shin-chan_Movie_13__Densetsu_wo_Yobu_Buriburi_3-pun_Dai_Shingeki) calls themselves "Guitar Samurai" it should be noted that this is a completely separate character. As seen in the credits it's shown that the character is "怪獣波田陽区" or "Kaiju Hata Yoku" (https://x.com/bakanemoti2525/status/994587422431170560). The character also has a Pixiv Dictionary page with
this name (https://dic.pixiv.net/a/怪獣・波田陽区).
I understand though that character could still be called "Guitar Samurai" because that is what most people know as the character.
As a solution to this, I think we should call this tag "怪獣波田陽区", "Monster Guitar Samurai" or something along these lines.
