I remember when watching this video 4 years ago,the ost like damn this is very beautiful and yet in that time i was like"wait a second,did hypergriph hiding this Honkai impact 3 genre of game??" this is arknights if they're making an hack and slash games after realize it's from kuro games. Man it's aged like wine,yeah i know the 3rd gen of PGR was an peak animation but this video still give me some chills with 1st gen construct.Kinda love to see they're improved so much and made a Wuthering Waves.
