Homeless and fresh out of employment, Mito Yamamoto faces familiar loneliness and despair. Luck is simply not on Mito's side; when he stumbles upon a cafe and cuts his hand, a strange server named Ruka Saotome licks the blood from his wound and even dramatically retches at its apparent disgusting taste. Offended and dispirited, Mito runs off to a bridge, hoping to put an end to his misery. But when Mito accidentally slips, he is miraculously saved by Ruka, who reveals he is a vampire. Unable to drink blood from just any woman for mysterious reasons, Ruka proposes that Mito become his thrall—a vampire's human servant and primary source of food. In this deal, Ruka will shower Mito with love to sweeten his blood, and Mito will gain a warm place to call home. However, there is an issue: Mito is a girl! Concealing her long, flowing hair and feminine body, Mito readily takes this chance and enrolls in the Hijirigaoka Boys' High School while working part-time at the cafe with Ruka. But the more Mito's bond with Ruka deepens, the more she struggles to hide her secret.

Bullied by his classmate and popular Newtube streamer Pakgo, Yoo Hobin's high school days are filled with humiliation and abuse. His troubles don't end there though; outside of school, Hobin slaves away at a part-time job to pay for his mother's hospital bills. One day, Hobin accidentally spills ramen on Pakgo's cameraman "Jiksae," tripping over a cord and disconnecting the other boy from his gaming stream. Finally fed up with his miserable lifestyle, Hobin fights back and ends up in a pathetic brawl with Jiksae. The next morning, it is revealed that the camera from Jiksae's stream had been recording the two boys' entire embarrassing fight. Moreover, the footage was accidentally uploaded to Newtube and had gone viral overnight, earning Hobin a whopping ten million won from viewership. Drawn to the money Newtube streaming can offer him and his mother, Hobin works together with unlikely ally Jiksae to produce more videos of him fighting and see how far Newtube streaming can take them. Taking on bullies like Pakgo and other seemingly unsurpassable opponents, Hobin will either rise to the top of the streaming world or finally meet a foe he can't outsmart.

When Leoleshea, a dragon god, is accidentally awoken from her sleep within a glacier, she demands this era's very best game player be brought before her. After a year of waiting, she meets Fay Theo Philus, an apostle—a human granted a supernatural ability called an Arise and thus given permission to challenge the gods in games. Fay and Leoleshea realize they share a passion for games, whether it be with cards or a battle of wits with a god. Declaring that she likes this human, Leoleshea allows Fay to call her "Leshea" and team up with her to play in the gods' games. Ever since the gods gave humans the ability to challenge them, they have promised to grant any wish after ten victories. Leshea desires to become an official god again, as she previously descended to the human world and lost her status as a divine being. Fay has only one goal: to find the woman who long ago taught him how to play games. Though Leshea and Fay quickly prove themselves to be a capable team, the gods will not allow them ten victories so easily: every game has its own unique conditions and hidden rules. Together, the duo will have to act as a perfect team to finally achieve their goals.
