真夜中ハートチューン [Mayonaka Heart Tune] #9

Two girls share a cozy gaming session on this volume's cover — a silver-haired, red-eyed girl in a teal hoodie reacts with wide-eyed enthusiasm while her braided, bespectacled companion in a yellow vest calmly holds the controller. The framing mimics a streaming or video-player interface, complete with playback controls and a chat-style overlay, cleverly reinforcing the series' digital and late-night atmosphere. Masaokuni Igarashi's artwork captures that warm, electric energy of staying up too late with a friend — a perfect snapshot of what makes Mayonaka Heart Tune so endearing.
