Kadokawa revealed at the Ikebukuro Halloween Cosplay Fest 2026 that cosplayer Enako will perform the opening theme while voicing a precinct staff member in the TV anime adaptation of Isshiki-san Wants to Know About Love. The romantic comedy series adapts the manga written and illustrated by Ayune Araragi, which follows two awkward police colleagues who enter a mock relationship to understand dating. The TV series will premiere on Japanese networks in January 2027 following an advance winter screening event in Tokyo. Kadokawa released a full trailer that gives fans their first listen to the opening track alongside voiced dialogue from the precinct cast [1].
Main Promotional Video Release at Ikebukuro
The reveal took place on October 31, 2026, during the annual Ikebukuro Halloween Cosplay Fest in Tokyo, a major street gathering known locally as Ike-Hallow. Kadokawa used the festival’s main stage ceremony to unveil the trailer and confirm winter broadcast plans for the new series [3].
The trailer provided the first sample of dialogue for four precinct colleagues who observe the central couple’s awkward workplace interactions. Voice actor Haruki Ishiya plays Danjuro Iwata, Takuma Nagatsuka plays Masato Nakatani, Hiiro Ishibashi voices Chikai Matsumoto, and Yu Wakui plays Rena Yamakawa. Production officials had named these four voice performers on September 24, 2026, but the Tokyo stage presentation marked the first public release of their character voices in animated scenes [6]. The video previews their reactions as the two lead detectives struggle to communicate [1].
Fans can attend an early preview at Ikebukuro HUMAX Cinemas on December 13, 2026, where attendees can watch the initial two episodes before lead actors Riko Akechi and Shuichiro Umeda join Enako on stage for a live talk session. PerEXP Teamworks previously covered lineup news in the voice cast announcement for False Angels. Fans can enter a ticket lottery through Ticket Pia that runs until November 23 [4].
Casting Cosplayer Enako as Station Nurse Nene
The casting assigns cosplayer Enako to the role of Nene Haneshita, a nurse who works in the police infirmary [2]. Official profile notes describe Nene as a calm, unhurried woman who enjoys broad popularity at the station while politely dodging personal questions about her private life [3].
Enako brings an established public profile to the anime adaptation, having built a following of over 6 million users across her social media accounts while appearing in TV shows, gravure magazines, and corporate ad campaigns. In early 2026, she entered the magazine cover hall of fame after securing first place in annual rankings for two consecutive years [6]. While she has made guest appearances at anime industry conventions for over a decade, this production gives her an unusual dual credit on a single anime project by pairing an in-show acting role with the performance of the opening theme song [5].
Her character Nene maintains an air of mystery away from the station, though she shares a close rapport with detective Rena Yamakawa [3]. Kadokawa released a solo art visual showing Nene in her nurse uniform with the casting notice [2]. Enako said she felt honored to join the precinct cast [6].
Workplace Romance Premise and Lead Characters
The story centers on Rinna Milford Isshiki, a disciplined young officer who passed police qualification exams to become an inspector at age 17. Rinna earns deep professional respect from coworkers for her competence, but her lack of dating experience leaves her helpless when new romantic feelings begin disrupting her daily work duties [2]. Voice actress Riko Akechi plays Rinna, capturing the inspector’s frustration as her composure slips whenever her detective colleague Meishi Rokutanda enters the room [1].
Shuichiro Umeda voices Meishi Rokutanda, a kindhearted but clumsily awkward detective who serves as Rinna’s regular investigative partner [1]. Because Rinna’s heart pounds when Rokutanda approaches, the two inexperienced officers agree to start a trial relationship to study how romantic affection functions in real life [2].
Manga artist Ayune Araragi launched the romantic comedy in Kadokawa’s Monthly Shonen Ace magazine on June 26, 2020, following an earlier iteration titled Rinna-keibu wa Kokyu ga Dekinai that appeared in Ichijinsha’s Monthly Comic Rex from October 2016 to December 2017 [7]. Kadokawa published the tenth compiled tankobon volume in Japan on May 25, 2026, and scheduled the eleventh print collection to arrive on December 24. North American publisher Yen Press licensed the series for English release, putting out the first volume on October 13, 2026, after previously announcing the manga under the localized title Ms. Isshiki Wants to Know About Love [2]. The steady manga release schedule provides ample narrative material for the TV season [5].
Music Credits Feature Cosplayer Enako on Opening Track
The anime’s opening theme song carries the Japanese title “Gō Yoku Koi o Seisu!?” [3]. The phrase translates roughly into English as “Strength Conquers Love!?”, and the upbeat track plays across the new trailer to establish a quick comedic tempo that frames the daily misadventures of the precinct staff on TV [1]. The release marks a fresh step for cosplayer Enako as she sings the main song for a TV broadcast [3].
Songwriter and music producer Yashikin wrote the lyrics, composed the melody, and arranged the instrumentation for the opening track. Yashikin incorporated rapid tempo shifts, bright brass accents, and playful vocal lines to reflect the comical misunderstandings that occur between the two main characters [4]. Having cosplayer Enako sing the title track allows the marketing team to showcase her vocal work throughout event appearances and future online spots ahead of the winter broadcast [5].
Kadokawa handles music production for the anime and plans to distribute the opening single across streaming services closer to the premiere [5]. Separate from the theme song, composer MICHIRU wrote the instrumental background score that accompanies dramatic and comedic scenes throughout the animated episodes [3].
Broadcast Schedule and Advance Ticket Sales
The anime will premiere in January 2027 with scheduled broadcasts on Tokyo MX, Kansai TV, and the satellite network AT-X [2]. Studio Sakura Create animates the series under the direction of Kazuya Komai, whose past credits include storyboard work and episode direction on BECK: Mongolian Chop Squad, Texhnolyze, and Tenjho Tenge [1]. Deko Akao leads series composition, bringing writing pedigree from popular comedy adaptations including Komi Can’t Communicate and Noragami [3]. The production brings together an experienced group of animators to translate Araragi’s comedic timing and expressive character art to TV screens [5].
Shohei Hamaguchi designed the characters for animation, Noriyasu Murata handled prop art, and Akiko Saito oversaw color styling, while art settings were directed by Yasutada Kato and Daisuke Horino managed photography with editor Yusuke Ueno. Masanori Tsuchiya directed audio recording. Studio Twinkle produced 3D digital elements under the supervision of CG director Satomi Nakajima [5].
Tokyo viewers can sample the early episodes ahead of the public TV run during a special advance screening event held on December 13, 2026. The theater program at Ikebukuro HUMAX showcases both debut episodes, followed by an appearance from cast members Riko Akechi, Shuichiro Umeda, and Enako. Ticket Pia is processing ticket lottery applications through November 23, 2026, giving domestic fans their primary opportunity to see the workplace comedy before its winter TV debut [4].
