Unlike Dr. Stone: Ryuusui, a successful 50+ minutes special released earlier this year, this fails to drive attention to its sequel. ''The Shining Will of The Sea'' is one of "The Seven Great Legends of Elysen", which Hajime and his gang experience in this special. The entirety of this episode/s is a battle scene. I don't find this necessary to watch for the continuation of the story and it doesn't add up to the plot. Rather, it introduces new characters which may appear in future of Hajime's journey. The quality is similar to the 2nd season of Arifureta, CGI dominating battle scenes and bright art. Don'thave any complains with this aspect. The studios (asread. and MOTHER) are doing a good job with consistency in the quality. Referring to the 1st season (which does not exist :d), the fans are blessed with potential sequels.

The dialogues are mainly Hajime's harem quarreling among themselves, making it no different than a generic special episode. The conversation follows Myu treating Hajime as a father and monopolizing him with her mom. XD. I'm no fan of a harem dominating plot either, and this special contains fanservice (not in terms of visuals).

I don't really have much to say about this, but I suggest watching since it wouldn't consume a great deal of time.
