Reception
The anime series' first episode received generally positive reviews from Anime News Network's staff during the Summer 2018 season previews. While finding the overall plot awkwardly delivered and lacking development, James Beckett praised Ton Baileu as the main heroine, the male cast having solid rapport with one another and the action scenes they take place in, concluding that fans of otome video games will enjoy it. Theron Martin praised the execution of a "pretty straightforward reverse-harem premise", highlighting the characterization of Ton and her male harem, and both the animation and soundtrack that culminate into "a respectable production effort." Rebecca Silverman also commended Ton as a character and both the character designs and fight scenes but found the episode overall to be "a messy and over-stuffed affair", concluding that viewers will enjoy it if they accept the melodrama and unintentional humor. Nick Creamer was critical of the show's slow opening, animation and staying too close to their given genre with its story but gave praise to the overall execution with its main cast having chemistry, engaging fantasy setting and Ton being a more than capable heroine, concluding that "f you're in the mood for a supernatural fantasy, it's definitely worth a look." Fellow ANN editor Christopher Farris reviewed the complete anime series. He also gave praise to Ton's leading presence carrying the show, along with the supernatural worldbuilding involving its cast of Twilights but found criticism in the off-model character art and a "general lack of complex, impressive animation" outside of the art direction and a few "battle-heavy" scenes in the final episodes that are hampered by lackluster villains, concluding that, "Even though most of its individual elements are pretty mediocre, Phantom in the Twilight isn't so difficult to recommend - there's enough strong material in here to elevate the show to "pleasant surprise" status, a good-enough romp worth watching if you have a craving for sexy supernatural boyfriends, and want a series that likely won't disappoint you." Silverman placed the series at number three on her top 5 best anime list of 2018, praising the action-harem plot being carried by Ton's no-nonsense characterization and the male harem having distinct personalities from each other, concluding with, "Add in some nice attention to folklore and literature, and Phantom in the Twilight becomes the reverse harem show for people who don't like the genre or who want to see it do something new."
