Limone is a powerful angel from the angel world, sent by the goddess Aphrodite to watch over Momoko Hanasaki and the other Love Angels and to grant them assistance whenever he is able. His name means lemon in Italian. He is a senior angel, holding a rank comparable to Momoko's mother Sakura in the angel world. In his angelic form, he descends from the sky on a flight of stairs and wields a sword as his weapon. To remain close to the Love Angels and observe their daily lives, he adopts the human identity of Kazuya Yanagiba, a popular upperclassman at the school and captain of the soccer team. Limone's primary motivation is to protect love and help the Love Angels fulfill their mission of defending the human world from devils. He serves as a guide and provider of magical tools, such as the compact case that allows Momoko to transform into Wedding Peach for the first time. His personality is calm, wise, and supportive, often offering advice from a distance. In the angel world, he had a close relationship with Angel Lily, which is later rekindled when the Love Angels rise to their roles. Over the course of the story, Limone develops from a mysterious celestial figure into a more involved ally who deepens his bond with Angel Lily and remains a steadfast presence for the team. His notable abilities include immense angelic power, flight, combat proficiency with his sword, and the capacity to take on a human form to blend in with the mortal world.
