Full Metal Daemon: MuramasaEnglish Release Teased by JAST - Why fans are hyped
JAST USA shared a very short video on Twitter, hyping up all fans ofMuramasa, who realized a localization is actually happening. Seeing JAST USA is the traditional English localization company for Nitroplus titles, manyMuramasafans dreamed to see this day come. In the past, JAST USA already releasedDeus Machina Demonbane,Saya no Uta, orSoniComiin English. Many were hoping the company would bringFull Metal Daemon Muramasaout of Japan one day, and it looks like it’s finally happening.
Full Metal Daemon Muramasais also particular in how the game uses vertical dialogue boxes. Which means an English localization will make it look drastically different, by adding horizontal dialogue windows instead. As reading English vertically would be way more unnatural than reading Japanese and no one wants to do that.
Personally speaking, I have yet to playMuramasa, and I’m starting to regret I missed my chance to do so while it was still only in Japanese. To brag about it on social media and rise as a true influencer. Jokes aside,Muramasais one of those things I’ve only ever heard praise of from those who actually played it, so I’m incredibly pumped as well. Anyways you can always hit me up on Twitter@A_iyane07if you wish to help further my influencer plans and wish to read even more Unneeded Opinions on niche Japanese things.
