Gary Oak : Thinks Death is an annoying loser.
Daisy Oak : Met Death once, thought he was cute, hasn't thought of him sense
Professor Oak : Helped Death arrange identification. He was initially a bit curious about his origin, but became focused on his work and forgot all about him.
Misty Williams : May have a slight crush on Death
Nurse Joy (Viridian City) : Met Death once, had a good impression of him as a young trainer. Nothing more.
Brock Harrison : Former gym leader of Pewter City. He respects Death a lot, both as a trainer and as a man who has many beautiful women as lovers, thus essentially living Brock's dream.
Sensational Sisters : Think Death is 'hot' but have no romantic interest beyond matters of the flesh/lust.
Leaf Verdant : She is in love with Death and has become his lover.
Bill Sonezaki : Respects Death as a researcher, but also dislikes him since he's dating his younger sister. He worries very much about Valerie, and would even go against Death if he found out that Valerie had been hurt.
Valerie Mache : Experienced love at first sight towards Death largely due to his belief in Fairy-Type Pokémon. She has become one of Deaths lovers.
Augustine Sycamore : Greatly respects Death as a fellow researcher.
Yvonne/Serena Gabena : Crushing on death but hasn't acted on it yet.
Diantha Carnet : Kalos League Pokémon Champion with a traumatic past. Do to a feeling f safety she got when around Death, she fell in love with him relatively quickly. This was because deep down she longed for a stable relationship with someone that she could trust, and Death was the first to be able to provide her with that. His tiny spark of divinity which acts as a slight bonus to his charismatic appeal, overcame her hesitance to truly trust any man, resulting in her falling for him.
Sabrina Natsume : Romantically interested in Death. He was the first person in her life able to overpower her and discipline her for behaving badly. Might have a hint of masochism to her, but mostly what she craves is a safe world where nothing can possibly hurt her. Originally she did that by pursuing whatever entertained her, but now she decided to follow Death's lead and to become his woman. Death has not slept with her due to her emotional immaturity, but he's helping her to grow up and might in the future.
Mallow Mao : Death met her outside of the Celadon City Gym. He learned that she was from Alola and that she was set to become the grass-type trial master in a couple months, but at the moment she was visiting Erika to train alongside a fellow grass-type specialist. She admired Death as a trainer, but as a tomboy she did not go straight to a crush, and at least for now has very platonic feelings towards him.
Erika Kono : Gym leader of the Celadon City Gym. She thought he was handsome, but since he already was surrounded by girls so she chose not to pursue such attraction.
Nurse Joy (Fuschia City) : Revealed that she is one of three Triplet, one of whom Death met in Viridian City. Was mildly amused by him.
Janine Anzu Kyo : Daughter of the Fuschia Gym Leader, currently on a journey to get stronger and one day take over the gym once her father steps down. She met Death and his friends on a visit back to her home when he and Leaf came to challenge Koga to a gym battle.
Ash Ketchum : Admires Death, and wants to beat him in the future, though he does understand that currently he is no match for him.
Mr. Applegate : President of a corporation that has television stations in every region. He was introduced to Death by Diantha, so that the 'show' RWBY could be broadcasted globally and create revenue for Death.
