I also believe theres enough to point Akuoumara in the spot as well honestly.
Noted as Royalty (kind of metaphorical)
this valiant "king of the eastern mountain" would become known as a brutal, savage "wicked king," or Akuou, to the people of Yashiori Island. — Debates of the viceroy of the east
Associated with sea monsters (mainly through Mounn)
This was also the beginning of Mouun's association with the giant whale named "Daikengyou." Legend has it that Daikengyou was a huge blind whale that had lived for five hundred years and four hundred years before that.
The dark depths of the ocean floor were its home, and the fishes of the deep and the moonglow-beauteous jellyfish were its faithful servants. Five hundred narwhals guarded its left flank and five hundred humpback whales played music to its right. — Life of Mounn the Shrine Maiden.These distant songs recount how she rode with Touzannou upon the back of a sea creature in the night.
Had a lover.
The songs of the Yuna Clan say that when the boy had grown into a young man, he was invited by Mouun the shrine maiden to swim together amidst tides lit by moon and stars alike. — Viceroys.
Seperated from her (granted, he did just die.)
She once frolicked with that reckless young man, whose only strength was his strength... "Once I bring that legendary Great Tengu's mask back, you have to keep our promise and finish that business."
"Sure, and if you're still so full of crap then, I'll get a whale to raise a wave large enough to wash that potty mouth of yours clean." – Mounn's Moon"One day, I shall set myself above Mt. Yougou, overlooking the palace of the Lord of Thunder." "I will have a joyful showdown against the legendary Great Tengu of Yougou upon the roof of Tenshukaku."
"...And then I'll bring that tengu's mask back to Ayame and Mouun as a souvenir!"
At last, the tides washed all their dreams away like towers in the sand.
The tengu's mask, shining like a crimson star, was shattered like seashore gravel amidst the chaotic battle— Akouomaru
Two other characters also have pretty interesting nods to Parsifal/Ajax; which would be Neuvillette and Kaveh.
Parsifal would flee to Liyue with nothing but a sword and a blue feather, and both of these men have a blue feather in their design. Even on the same side of their head.
Parsifal loved drinking with his friends which fits Kaveh quite well. He also became a depressed alcoholic after suffering in his life, which also sounds a lot like Kaveh.
Neuvillette's idle is a reference to the silver chalice with blue gems that Parsifal stole one night, and then gave the gem as a courting gift to a blue-eyed maiden he fell in love with.
Both Kaveh and Neuvillette just so happen to be big fans of blue-eyed women; namely Nilou and Focalors/Furina. They enjoy watching them perform and hold a great deal of respect for them. Focalors even dies tragically like Parsifal's lover.
Neuvillette "fell" into a different world and fought a "sea monster", the all-devouring narwhal. Wriothesley with his giant-ass boat at the end seems to be a reference to Captain Skipper, whose Chief Mate became Parsifal (aka. Neuvillette) after he fled to Liyue.
Neuvillette went to visit Liyue during the Lantern Rite, "the land of gold".
Kaveh, if I recall correctly, was talking about having some construction projects involving Port Oromos which indirectly ties him to the sea. In fact, I believe he was also mentioned as the architect who worked in that bottle world run by an Oceanid which associates him with Fontaine, primordial water, and Neuvi to a degree. We all know his mother remarried to Fontaine, but I'm not sure if this bit counts as a hint.
not exactly canon, but it should be noted that in the recent KFC collab Kaveh seems to embody the aristocratic Phantom Thief who stole from the rich, which is exactly who Parsifal was. Furthermore; the collab is presented as a play performed by actors, and Parsifal was known for his love of play-acting (which ties him to Childe as well iirc since he acts in plays sometimes)
There may be more things I missed, but this is what stood out to me the most. Both Neuvi and Kaveh, like Childe, seem to be great with kids. That might be another thing.
