Krishna is an employee at the ramen shop Red Cat Ramen, responsible for making the restaurant's in-house noodles. She is a tiger, specifically a cross between a Siberian tiger and a Bengal tiger, and was born and raised in a zoo before being recruited to work at the shop. Despite her imposing size and naturally fierce appearance, Krishna is extremely timid and shy. She dislikes confrontation and is easily frightened, often described as a scaredycat. Her gentle, quiet nature contrasts with her intimidating looks, and she finds reassurance in the daily routine of the noodle room. She enjoys being brushed and cared for by her colleagues, activities that help her relax and feel at ease. Krishna is motivated by a desire to peacefully contribute to the shop and takes quiet pride in her craft. Her role is vital to the ramen's quality, as she prepares fresh noodles using her own paws, a method featured in the shop's operations. She works alongside the other feline staff members, including head chef Bunzo, owner Sasaki, sous-chef Sabu, and customer service manager Hana, as well as the human part-timer Tamako Yashiro. They all treat her with kindness and patience. Over the course of the story, Krishna gradually becomes more comfortable within the supportive environment of the shop, though her core shy and timid personality remains a defining trait.
