Towa Akatsuki

(eng) Not a single one of these is the legal name, so far as I've been able to ascertain. Many of the WN/LN/Manga related sites show considerable confusion as to which of these names are associated with the same person.
The Syosetu Author page is maintained by this individual; if the title shows up there, it does pertain to this chap. That page gives とーわ／朱月十話 as the names written under.

The Twitter account, とーわ／朱月十話 @akatsukitowa, contains novel covers and illustrations clearly associated with these works, including The World's Strongest Rearguard.
Given the Twitter account name, 'Akatsuki, Towa' would appear to be the most reasonable author main entry.
