Delmon’s Wife

Based on her brief flashback appearance, she was a young woman with a gentle aesthetic — long, dark, straight hair past her shoulders, kind expressive eyes, and round-framed glasses. She is depicted in simple, light-coloured clothing, and her final appearances show a slightly frailer build — the visual register of someone whose health was declining.

The predominant image of her in the series is the tulip scene: her expression receiving the flower Delmon grew. That expression — the specific gratitude of someone who understood exactly what the gesture cost — is the image that Gachiakuta established as Delmon's foundational memory.

The Tulip — The Vital Instrument's Origin

Her single active scene is the flashback detailing the origin of Delmon's power. She had a dream — to see a real flower. On the Ground, real flowers are extremely rare and valuable: the Sphere gives them to the sick as a luxury; the Ground simply does not have them. Delmon spent years attempting to grow one specifically for her. He eventually succeeded — a tulip, cultivated from the Ground's hostile terrain — and brought it to her.

She received it and said: "I finally get to see a real flower, and it's all thanks to your hard work, sweat, and tears. Thank you." The sincerity of that exchange — the depth of what both of them had invested in the gesture — is what imbued Delmon's gardening hose with Anima. It became Thirst Quencher. His desire to make things grow big and strong was entirely for her, and the instrument carries that origin into every use.

The Bouquet — Present-Day Devotion

Following the Penta mission, Delmon arrived at the medical ward carrying a bouquet. Rudo saw it and suggested giving the flowers to the injured patients — Gris and Zanka. Enjin explained that Delmon had worked incredibly hard to obtain them and that they were specifically "for his wife who's gone." The flowers were not for the living injured. They were for her. Delmon still brings her flowers. He made it his goal to fill the house with them when she was alive, and the goal did not end when she did.

• Her name has not been disclosed in the manga or in any official character profiles. She is referred to by Enjin as "his wife who's gone" — the most exact description the series provides for her current status.
• The tulip she received is the series' most economical symbol of life and care in a world defined by discarded objects. Flowers on the Ground are, as Enjin notes, as rare and valuable as the Sphere considers them luxury gifts for the sick. Delmon grew one through years of sustained effort. She called it the first real flower she had ever seen. The same hose used for watering is now Thirst Quencher.
• Delmon's Vital Instrument origin is one of the series' most explicitly peaceful: he did not need to fight, survive, or endure loss to awaken his power. He needed to want something good enough for someone he loved, and care for it long enough that the caring accumulated Anima. The loss came afterward.
• The Chapter 48 bouquet scene is the most understated grief beat in the series. Rudo almost gave the flowers to living patients. Enjin stopped him. The flowers were for her. Delmon brought flowers to someone who cannot receive them and kept bringing them. The series presents this without commentary.
• The Penta arc's manipulation of Delmon — causing him to see Amo as his wife in an illusion — worked because his wife is still the person whose safety overrides every other consideration in his psychology. She is gone. He is still operating as though she needs protecting. That wound being the target of Amo's power is one of the more precise pieces of characterisation in the series' roster of manipulations.
