Renge Inui

Often acting as the group's energetic cheerleader, this pint-sized companion brings a high-spirited, albeit occasionally whiny, energy to every adventure. Despite an obsessive appetite, she maintains a slender frame, though she occasionally sports a small belly after large meals. Alongside her beloved pet kitten, she navigates life with her two identical younger sisters, Men-Men and Mikan. She shares a close bond with Tsukio, frequently supporting him with breakfast money, all while sporting a charmingly Astro Girl-inspired appearance.
