The product is an energy drink for tired salary-men called Arinanim V-Drink (V for vitamin). That’s why the mascot is called Ariman. “Arnold” becomes “A-ru-no-ru-do” in Japanese, that’s why they call him “Shu-wa-chyan” instead.
Shuwa-chan keeps saying “V”, “V”, but Japanese has no similar sound, so they render it a “bu-i “ (ブイ), and that’s what you hear coming out of his mouth.
