The television adaptation of Hotel Inhumans has added a new voice to its second run. Japanese voice actress Mitsuki Saiga will play Sekiya in the broadcast about a luxury hotel that caters to contract killers, MyAnimeList reported on October 29. The casting arrives as Hotel Inhumans Season 2 continues its weekly run on Japanese television and streaming services. Ao Tajima created the original web manga about concierges who serve assassins, and this casting introduces another guest whose strange habits stand out in public [3], [4].
Mitsuki Saiga Joins the Cast as Sekiya
Sekiya enters the story as an unusual figure. An elementary school student named Tsukada Eriko notices her on the morning train, where passengers usually keep to themselves. Sekiya reads books about murder. She doesn’t hide titles about deadly poisons from nearby commuters [3]. Her quiet demeanor hints at dark business [4].
Saiga brings decades of voice acting experience to the role, earning recognition across anime fandom for her distinct vocal work in characters that blur conventional gender lines. She often voices calm, androgynous characters who project quiet authority on screen. Her lower register suits Sekiya as she checks into the hotel for shelter from rival syndicates [3],. The story treats these criminal guests as regular hotel patrons [4].
Studio staff released a new key visual with the casting news, using classic noir styling with heavy shadows and sharp lighting to set a tense mood for upcoming episodes as new guests arrive at the hotel on the border of death. In this environment, client demands go far beyond normal room service. Concierges must solve life-or-death crises without causing a disturbance in the front lobby [4]. Sekiya’s entrance introduces fresh danger for the desk team. Her strange reading habits on the morning train connect straight to underground assassination contracts, pulling the front desk workers into volatile disputes that threaten the establishment’s long policy of strict neutrality [3],. Hitmen expect complete discretion whenever they step onto the premises [4].
Hotel Inhumans Season 2 Production Staff
Director Tetsuro Amino leads the production team at animation studios Bridge and Aisle [3]. Veteran writer Shoji Yonemura oversees the series composition by adapting Ao Tajima’s original manga, while Shingo Fujisaki provides character designs that capture the noir style of the cast. Art director Yoshimi Umino oversees the background art. He designs dining rooms and private suites for deadly guests [4].
The creative crew brings together experienced anime personnel across multiple departments, with Haru Yamada supervising sound direction with Tomokazu Mitsui on sound effects while musician Koharu from the duo CHARAN-PO-RANTAN composes the background score [2], [4]. Visual departments feature director of photography Toshiyuki Sadamatsu, color designer Fuyuto Muraguchi, background artist Junko Nagasawa, and film editor Daisuke Imai. Special effects artist Hiroshi Asami provides visual effects for gunfights, and Haruka Matsushita handles sound recording with assistance from Sarasa Yoshida. Bridge and Aisle keep the stylish noir atmosphere of Hotel Inhumans Season 2 consistent as the weekly narrative moves between quiet luxury hotel corridors and chaotic gun battles in city streets [2], [3].
Seven companies support the television series. TV Tokyo, Dentsu, TV Tokyo Music, Good Smile Company, Sound Team Don Juan, Shogakukan, and DMM.com serve as the producing partners. Executive producers include Yoshikazu Beniya, Ryousuke Nakaji, Junya Okamoto, Hayato Saga, and Noboru Yamada.

Returning Concierges and New Branch Arrivals
The core narrative stays anchored to the hotel’s front desk concierges. Voice actor Yusuke Kobayashi returns to play Ikuro Hoshi, a rookie concierge who dislikes bloodshed and tries to resolve difficult client requests peacefully despite his conflicted feelings about assisting contract killers. Still, he takes pride in delivering spotless hospitality to every registered patron [3].
Hinano Shirahama returns to voice Sara Haizaki, the veteran concierge who protects the hotel grounds, commands deep underworld connections, and enforces unbending neutrality across the entire facility [3], [4]. She mentors Ikuro through his early mistakes and teaches him how to handle lethal patrons without breaking hotel etiquette [3].
The second season introduces fresh faces to the lobby team as well. Hina Yomiya plays Shiba Kirihara, a young concierge who transferred from the London branch and openly admires Sara’s professional composure. Early episodes also feature Shoya Chiba as guest character Subaru Yoda, adding friction to daily routines behind the counter. Concierges never decline a request from a paying guest. They provide registered visitors with fresh passports, customized firearms, and complete body disposal, but they also preserve the quiet elegance of five-star luxury hospitality without showing fear [3], [4]. Hitmen check into the hotel knowing that staff members will protect their secrets and treat them with courtesy [3], [4].
How Hotel Inhumans Season 2 Adapts the Manga
Author Ao Tajima created the original web manga about luxury hotel services and organized crime, inspiring a television adaptation that returned for its second season after season one concluded in September 2025. Early episodes adapt the “Piano Lesson” story arc, which follows a teenage assassin working undercover at a local school during a contract [3].
The series balances quick action scenes with character-driven drama. On MyAnimeList, Hotel Inhumans carries an organized crime theme and holds a PG-13 rating for viewers aged 13 and older, recording 7,641 members and a popularity ranking of #8305 [2]. The story explores why people enter the killing trade. It proves that even ruthless hitmen carry regrets and family burdens. English volumes of Tajima’s manga continue to reach readers as television viewers follow the weekly broadcast. Ongoing print releases give international fans a convenient way to compare the pacing of animated television episodes with the original illustrated panels drawn by Tajima. Readers find extra background on hotel rules in the manga volumes [3].
Bringing Sekiya into the storyline expands the world beyond the hotel walls. Previous episodes focused on assassins who actively check into the building, but her presence shows how killers blend quietly into commuter crowds [3], [4]. What kinds of requests will Sekiya bring to the desk? Concierges must prepare for another dangerous visitor [3], [4].
