There is little to no information known about the title, but there was a teaser site launched late last night which has a countdown timer leading up to 10 June 2021. On top of the countdown timer, there are a bunch of names listed which are presumably the staff working on the title, but most of the names are still blocked out (literally). There is also a Japanese phone number listed on the web page that when you call it, you’re greeted by some pretty cryptic messages, some gurgling, and a male character screaming.
Some of those names that can be made out are: Kazunari Suzuki, Ryotaro Ito, Tsukasa Masuko, and Aya Nishitani. Suzuki was the writer for Shin Megami Tensei: Digital Devil Saga; Ito was also a writer for the Shin Megami Tensei series; Tsukasa Masuko was a composer for the earlier titles in the Shin Megami Tensei series; and Aya Nishitani is a novelist whose stories inspired the complete Shin Megami Tensei series. Needless to say, the four names that we know so far are massive and we might be in for a very big treat.
With Monark supposedly being fully unveiled on 10 June 2021, we will hopefully get a bunch more information regarding the title and what we can expect from it.
