@Eminent I agree. the anime has me hooked so far and I was disappointed to find there hasn't been a licensed English translation yet. I think I saw that Seven Seas picked up the manga but there are only 20 chapters or so... I want the LN ASAP (and I saw a few people say it has AoaB vibes so I'd definitely read just based on that)
It’s a long “o” so I would personally romanise as Sanda Shirou. Although the publisher of this specific book is using Nihon-Shiki, “Sanda Siro,” they themselves use Shirou on Kakuyomu: https://kakuyomu.jp/users/shirou_sanda
Note that this is in Japanese order (given name last), whereas you’ve given the illustrator’s name in western order (given name first).
I discovered this series after reading the first volume of the manga version of The Oblivious Saint Can't Contain Her Power: Forget My Sister! Turns Out I Was the Real Saint All Along! , but after reading the LN version I do not know if this series from Volume 2 to 5 will be good (Volume 1 is available in Web Novel Format)
