Painful Signal is described as a Homecoming Wings Memoria. The tagline 'To feel you, no matter what the price might be' lands the entire cyborg-arm arc in a single line: the sensation he has lost in his right arm was warmth, softness, touch — the ability to feel her through physical contact. He is aware of the loss. The 'price' is not metaphorical; it is the literal trade made when his arm was rebuilt. The Memoria is the most direct emotional articulation of what the mechanical arm costs him in terms of intimacy.
