To a Different World with Toapugu!?

Tadano Taro, a TRPG enthusiast, agreed to play a session at the invitation of a friend. He hastily filled out his character sheet and opened the front door... only to find himself in a vast grassland covered in green. Strangely, his appearance had changed to match what he had written on his character sheet. Convinced there must be a reason for this situation, he decided to search for others in the same circumstances. A beautiful silver-haired, red-eyed girl. However, her true identity is an unusual combination: a holy priest vampire. A girl calling herself "Abyss" travels, wielding the power of TRPG.
