An adventure diary with three yandere girls.
About
In the world of sword and sorcery, Asgards, a grand ceremony was being held in the capital of the Kingdom of Marland. The first princess, Sarthia, had just received the revelation appointing her as the Hero. The tomboyish Sarthia, bored by the stiff ceremony, sneaks out into the city where she happens to pass by Guest and falls in love at first sight. Under the pretext of recruiting a party member, she tries everything to force a relationship, but... To ensure safety, adventurers are ranked by the Guild. The ranks are as follows: SS-Rank (Calamity) S-Rank (Monster) A-Rank (Advanced) B-Rank (Standard) C-Rank (Low) D-Rank (General) Quest recommendations are also set based on these ranks.
