Kyuuketsuki Sakka, VRMMORPG wo Play Suru @COMIC summary:

Renge Haruto, a novelist who has lived since the Kamakura period, is a vampire with an aversion to blood.
Due to his catastrophic lack of technological skills, he has been leading a super analog lifestyle. However, during a meeting one day, his editor suggests that he write his next manuscript within God of World, cutting-edge VRMMO game.
With both excitement and anxiety, he steps into this new world, only to be greeted by sunlight for the first time in hundreds of years and a variety of delicious foods that he could never enjoy in reality. He quickly becomes enthralled with the game…
"Wait, what? My brainwaves aren’t human — so I’m being treated like an NPC?"
"A cardiac arrest and an ambulance is being called? Whoa, whoa, hold on a second!"
This gentle vampire, a total newbie gamer, starts hopping between the game and the real world. Unknowingly, he begins to drag those around him into a slapstick VRMMORPG adventure!
