"Raiden Forgetting River Guardian Mei."
"Huh?"
Mei looked completely bewildered, while Acheron seemed lost in thought.
Who was she calling? Acheron had no idea.
"Raiden... Forgetting River Guardian?"
Mei was quite familiar with this naming style. Though it was a little irregular according to the surname—received name/official title—ancestral surname—given name format, simply put, it meant—Raiden Mei.
God knew why the name was proper without being entirely proper. Maybe Raiden had always been the surname?
Still, this naming style itself was more like a formal written signature. Few people would actually introduce themselves that way.
If Mei used that style, her name should have been "Raiden Forgetting River Guardian Hokushin Mei."
What did she have to do with Hokushin?

As for why surnames had to be divided into one's current surname and ancestral surname, naturally it was because ancient people had far too many bizarre tricks. Branch families changing their surnames was nothing special.
For example, Tian Rangju, also known as Sima Rangju—how many surnames did his family involve? Their ancestors had the surname Chen, which was changed to Tian. Sima Rangju then derived Sima from his official position. Later, Wang Mang was also from this Chen lineage that had changed its surname.
And the Chen surname could also be linked to Gui. Mm, things like the Gui clan of the Chen surname—if you forcibly traced it back far enough, you could even find mythological relatives.
