Raid is a very opportunistic person, seeking any chance to get what he wants, even threatening bodily harm. He is also over-confident, embellishing his own talents despite being unable to completely transform into a weapon. Reid can also be verbally insulting, calling people like Meme dumb, but still wanting her as a meister. Overall, Raid is a cocky, jerky person who is quick to anger when provoked.
After his and Hao's defeat at the hands of Anya Hepburn, however, he and his meister became more humble.
Before his defeat, his hair consisted of loose, flowing spikes and bangs with an irregularly long one on the left side of his face. He wore a unbuttoned blue bussiness suit over a white dress shirt along with a red tie, and blue slacks held up a black belt. He also wore brown dress shoes. He also wore multiple ear piercings, including two metal hoops on the left ear and a silver ear cuff and a gold stud with a red sphere imbedded within it. Raid almost always had a permanent smirk across his face sporting very thin eyebrows. He retains this appearance throughout the anime.
After his defeat, and a lecture from Anya on better dress for better fighting, Raid followed his meister's example and stopped wearing his hair long and removed all ear piercings. Although still blonde and still with piercing blue eyes, his smirk is replaced with a more polite smile. His hair is cut shorter and his bangs are swept away from his eyes, although still asymmetrical. He no longer wears his business suit, instead sticking to his dress shirt (with the sleeves now rolled up), tie, slacks, and shoes. His change in hair and attire also may be influenced by the summer heat.
Full-Weapon Transformation (全身武器, Zenshin Buki): As a Demon Weapon, Raid is capable of transforming himself into his human and weapon form at will. Although he isnt capable of a full weapon transformation, he is able to move his forehead anywhere on his weapon form at will.
- Sword (刀, Katana): Raid can transform into a short sword but due to inexperience, he is unable to transform his head completely. Initially, Raid could not transform all of his head later, he was able to transform all but above his jaw into a weapon.
- Wavelength Control (波長コントロール, Hachō Kontorōru): As a Demon Weapon, Raid has some skill in controlling his Meister's wavelength in his weapon form.
- Soul Resonance (魂の共鳴, Tamashī no Kyōmei): Raid has some rudimentary skill in Soul Resonance that enables him to connect to his Meister and understand his speeches.
Raid, with Hao, appears as as the first antagonist for Tsugumi Harudori, whose duel allows her to demonstrate her courage. Raid also appears initially as comic relief, given his inability to transform completely into a weapon and his embarrassing defeat with Hao.
Raid was one of the new students of Shibusen and came along with Hao late to class. After finishing the day's lesson, their teacher Sid Barrett dismissed them and all other students. Sid also warned late students to arrive to the next class on time.
After leaving class, Hao asked Raid what he wanted for a partner. Raid replied that he would rather have a cute, female meister rather than spend time in the boys' dorm. Noticing Meme Tatane and assuming she was not bright, Raid attempted to flirt with her to become his meister. Tsugumi Harudori, eavesdropping on this conversation, was noticed by Hao, whose comments intimidated Tsugumi to run away in fear. However, when Meme did not accept Raid as her weapon Tsugumi returned and took Meme's hand to escape these bullies. Hao stopped the two NOT students, as Raid claimed the two boys were only looking for partners. Noticing this confrontation, Anya stood up for Tsugumi and Meme, openly insulting Hao and Reid to their faces.
Raid challenges Anya to a duel, who accepts, asking Tsugumi to turn into a weapon. Raid turned into his weapon form, a sword, but he was unable to transform his head. While Tsugumi had difficulties transforming, inspiring words from Sid, who was observing the duel, and memories of Maka Albarn's encouraging words, allowed Tsugumi to finally transform into a halberd. Anya and Tsugumi swiftly defeat Hao and Raid, whose injuries prompt Clay Sizemore to find Medusa Gorgon at the infirmary.
Before they are taken to the infirmary for medical treatment, Raid transformed back into his human form, with Anya standing above him and Hao. She demanded the two punks stand up, as she lectured the two that their failure was because they focus more on physical appearance than skills at combat: she demanded the two remove their jewelry and cut their hair so they could move more easily and see better in combat. When Raid commented that girls are interested in cool, flashy guys, Anya informs the two that girls prefer people who can face themselves, who can "be cool without acting." This information impresses Hao and Raid, who agree to follow "Anya-sama's" lesson.
Anya then took Hao and Raid through the DWMA to observe EAT student Ox Ford, who studies and physical training are for the sake of someone he loves. When Hao and Raid then see Ox's work still fails to impress Kim, who thinks Ox's haircut makes him look creepy, the two students are shocked at Anya, who had told them earlier that girls care less about flashy appearances and more about substance. Anya responds, "Everything has its limits."
In the summer, Hao and Raid return to NOT classes at the DWMA. During Sid Barrett's class on weapon control, with Maka Albarn and Soul Eater in attendance, Hao is the first student called forward to demonstrate Raid's ability at fully transforming into a weapon. They are gently mocked by Anya Hepburn, who is curious to know whether the two have learned anything since their duel on the first day at classes. While Raid is able to transform more of his head than before, he cannot transform above his jaw. Maka and Soul explain that the two must improve their ability at Soul Resonance in order to improve their abilities. Although their transformation was insufficient, Tsugumi Harudori is impressed with Hao and Raid's persistence to train more to improve their Soul Resonance, especially compared to how she remembers their prior behavior.
- Although his name is spelled "Raid" in the Yen Press English translation, his name is also spelled at times as "Reid."
- The scene in the final episode of the Soul Eater NOT! anime, in which Hao and Raid were defeated by Patty Thompson during their attack on the girls' dormitory, mimics their defeat against Tsugumi and Anya: Hao's pants rip, and Raid coughs up blood.
