Development
Chinatsu Kurahana served as the game's lead character designer. She was chosen due to his prior work on '' Uta no Prince-sama'', with the style employed there being used to help reinforce the "glamorous, aristocratic society" the various noble characters lived in. She directly influenced many design aspects of the various characters. The youth of the students was also a focus, with the game being built around their growth. The calendar system was also implemented into the game to make it so players had to pick and choose what they wanted to do and which characters they wished to interact with. The concept art for the game was contractually done by Kazuma Koda, known for his previous concept art of ''Main characters

An attempt to revive Sothis is made during the events of the game, but is interrupted by the arrival of Edelgard. She eventually merges her soul with Byleth's, no longer appearing before them. Sothis's child-like appearance was chosen to represent the fact she was half-way to being brought back, with her being unable to fully restore herself. In ''Three Hopes,'' Sothis is capable of controlling Byleth's body, and does so on several occasions. Depending on the route, she either joins Shez alongside Byleth, or dies with them.

: The Gatekeeper is aReception
The characters of ''Fire Emblem: Three Houses'' have received a generally positive reception since the game's release. The game's wide variety of characters and personalities have been praised, both for their relatability and their emotion. They have been cited as a well-rounded and engaging cast, with their interactions with the protagonist, Byleth, being a particular highlight. The morally grey characterization of the various factions during the war phase of the game, with their dubious mix of good and evil helping build the depth of their characters. The inability to satisfy the wishes of every character was highlighted as well, as it forced the player to decide which characters they wished to side with. Alanna Okun, writing for ''Polygon'', highlighted this depth, stating that "...you become intensely acquainted with their quirks and proclivities... It would be hard to overstate how much I think about these people who don’t exist, how many soft spots I’ve developed for two dozen fictional students living in the year 1181. Whenever I play, which is practically every day now, I feel made of soft spots." She also highlighted the comfort that many of the in-game support conversations provided for her. The interactions characters have with the world were also highlighted, with the interactions and storylines of characters helping to make the monastery "feel alive." The game's "lost items" system, which involved Byleth returning lost items to their owners, received positive commentary, citing how it helped build depth with the cast. The cast of the game has been widely popular with fans, spawning large amounts of fanart and fanwork. Many specific members of the cast have also been met with particular praise for their various storylines.References
