“Remember, we have to keep this a secret, or it could be national news,”

Desumi Magahara is the Reaper Princess. She is also the deuteragonist of the manga Love After World Domination.

Desumi is a beautiful high school student with neck-length blond hair that has bangs swept to the left side and green eyes.

Her Gekko Battle Gear is a kind of revealing dark blue demon-style outfit with bunny-like ears and thigh-high boots.

Desumi is kind and lovable, but because of her absurd strength, many at Gekko find her scary. Many of her subordinates make offensive remarks about her, and despite being strong on the outside, deep down, she is just like any other girl and gets hurt. She is actually very kind and has always sacrificed herself for others. Joining Gekko wasn't something she wanted to do, but it made her father happy.

She is prone to getting jealous, as shown when Fudo garnered much attention from numerous women on different occasions. However, she admits that she knows better than anyone that Fudo wouldn't cheat on her and it's more so that she's afraid of whether or not someone like her is suitable for him. She couldn't continue hurting him any longer and it was only until he hugged her and declared his love only for her that she could finally stand strong again.

Desumi's strength has been remarkable ever since young, to the point of unintentionally closing down a dojo after defeating the dojo master. Her parents were former members of Gekko, so ended up in the same profession despite not wanting to.

She saved Haru Arisugawa when she was attacked by two thugs and told her to become stronger.

When Red Gelato asked her out, Desumi became disappointed in him due to believing that he was exploiting her inexperience in love. She also brought up the negative rumors that made her undesirable, but Fudo shot them down since he knew her real side, as he was an avid follower of her social media. Seeing Fudo's earnest love confession, she accepted his feelings and the two began dating.
