Scarlet Nexus is a colorful adventure slasher game with a third-person view in the Japanese style from the creators of the Tales of series. In the distant future, humanity is faced with the Others — aggressive bouquets with women's legs. The fate of humanity lies in the hands of an elite group of OSF psionic soldiers who must eliminate the threat. The main character is Yuito Sumeragi, who, according to the plot, joins the squad to fight the Others who threaten humanity. In the game world, the human brain is connected to a social network called Psynet. This allows people to use social services and receive new information. By being connected to the Psynet, Yuito will be able to borrow abilities from other people and use them in battle against enemies.
