Your Skyblue is a limited 5-Star Memoria released June 8, 2026 as the centrepiece of Caleb's 2026 birthday celebration, part of the Clearsky Daydrift event (June 8–15). The premise draws on Caleb's backstory: his birthdays since childhood were always shared with others or taken away by something else — missions, the Academy, the circumstances of his double life. For the first time, MC plans a birthday that belongs to no one but him. The story involves inviting Caleb to the other side of the world to fulfil a long-held wish of his. The culminating scene places MC in the copilot's seat beside him as the perfect sunset falls over the horizon — a deeply personal image for Caleb, whose identity as a pilot is bound up with his relationship with the sky. The phrase 'Your Skyblue' frames the sky itself as a gift: the sky belongs to him, and sharing it with MC becomes a memory that belongs to both of them. The event also distributed: the Caleb: No-Return Night rerun banner; a returning Caleb: His Gravity 3-star; a Caleb Daily Outfit; and event currency for the Clearsky Daydrift shop.
