There's actually a lot of misinformation going around about the relation of Seikai to Hime-Seikai and Jukai.
Jukai and Hime-Seikai is actually not officially known to be related to Seikai. The similarity in appearance is not known to be anything beyond coincidence, although of course there are reasonable doubts to that as well. In any case, Jukai and Hime-Seikai are siblings of each other though.
Seikai itself is a very old variety found in the wild over 200 years ago. Seikai is self-sterile and all Seikai are divisions of each other.
Hime-Seikai and Jukai on the other hand were found in Korea among the selfed seedlings of a rather normal looking Japanese wild plant. While Hime-Seikai and Jukai are themselves also self-sterile, there were numerous Hime-Seikai and Jukai offspring in that original selfing of the parent, and it is said that subsequent selfings of that parent plant have resulted in additional Hime-Seikai and Jukai offspring. Among all of the offspring, any of this type that have pigmentation in the stem and root tips are named Hime-Seikai, while any that do not produce any anthocyanin pigmentation are named Jukai.
References for the origin of the variety can be found on the Korean Neofinetia Association official description of Hime-Seikai and Jukai varieties. Both are registered in Korea:
Hime-Seikai:
희청해(姬靑海)
Jukai:
수해(樹海)
Corroboration can also be found in Japanese on Page 203 and 249 in the book:
