A Day With Maron is an omake and the the one hundred and sixth.five chapter of To Love-Ru.
Haruna's dog, Maron, introduces himself as a proud Boston Terrier. Maron then explains that he is actually Haruna's sister, Akiho's dog, but she is rarely home, so Haruna take care of her. Maron then remarks about his life, such as how he wishes Haruna would get a different kind of dog food, but he can't complain because he is a freeloader after all. Maron then explains that his sole mission is to protect his master, at all costs. Maron then states that he hates taking baths, but he won't let Haruna know that. Maron then says how his life isn't easy.
