Kroi Release New Single 'All in,' Opening Theme for Liar Game Second Season on July 13

Kroi, the genre-blending five-piece band known for their fusion of R&B, funk, soul, rock, and hip-hop, has launched a new single titled “All in” on July 13, 2026. This track serves as the opening theme for the highly anticipated second season of the psychological suspense anime LIAR GAME, which is currently airing in Japan and streaming globally outside of Japan and China.

The song “All in” reflects the intricate and tense atmosphere of LIAR GAME, a series rooted in deception, psychological warfare, and complex mind games. Kroi’s vocalist, Leo Uchida, delivers sharp rap verses that mirror the anime’s intense narrative of strategy and betrayal. The composition is driven by dynamic guitar riffs, a compelling bassline, and a funk-influenced rhythm that collectively underscore the emotional and suspenseful tone central to the series.

Leo Uchida has expressed a personal connection to LIAR GAME, having been a longtime admirer of the franchise since his youth. He aimed to channel the series’ layered storytelling, capturing the pervasive tension and ambiguity of truth and lies through Kroi’s distinctive sound. The track integrates melodic elements with darker, textured soundscapes, exploring the psychological complexity that the anime portrays.

Accompanying the single release, Kroi debuted an official music video directed by Ryō Suda, marking the band’s initial collaboration with the filmmaker. The visual presentation is notable for its ambitious 90-second continuous shot at the beginning, designed to evoke the song’s title “All in” and the theme of unwavering commitment symbolized by ultras or devoted supporters. The video’s raw energy and uninterrupted sequence visually parallel the song’s intensity and thematic focus on relentless pursuit and determination.

Looking ahead, Kroi is set to embark on their “JUNGLE” live tour starting in August 2026. This tour will cover 10 shows in six major Japanese cities, including Yokohama, Nagoya, Sapporo, Fukuoka, Osaka, and Tokyo. Notably, the tour features guest appearances from prominent artists such as Rekishi, iri, KIRINJI, and the Tokyo Ska Paradise Orchestra, marking Kroi’s first collaborative concerts in nearly two years. The performances will be held at Zepp venues, known for their acoustics and vibrant atmospheres suitable for rock and pop acts.

Formed in 2018, Kroi emerged onto the major-label scene in 2021 with their debut album “LENS.” Since then, the band has cultivated a diverse fanbase both domestically and internationally, highlighted by their first Asia tour in 2025 which included stops in Seoul, Taipei, and Bangkok. Their expanding international presence has been bolstered through multiple anime theme song contributions, including recent singles like “Method” for SAKAMOTO DAYS and “Water Carrier” for SAND LAND: THE SERIES.

LIAR GAME itself is a well-established property that has captivated audiences for over two decades. Originally a suspense manga serialized from 2005 to 2015 by Shinobu Kaitani, the story revolves around Nao Kanzaki, a college student thrust into a high-stakes psychological game involving deception and massive financial risks. The manga’s previous adaptations include a 2007 live-action drama, a 2010 feature film, and a 2023 stage production. The current anime is produced by Madhouse, a studio renowned for acclaimed titles such as Frieren: Beyond Journey’s End.

The new anime season continues to explore the intricate battles of wit and mistrust that define the LIAR GAME universe, with Kroi’s “All in” amplifying the series’ dark and suspenseful mood through its bold musical approach. The band’s integration of varied musical styles aligns with the multifaceted nature of the anime’s narrative, supporting the psychological depth and unpredictability present in the story.

As the anime and the single gain traction, fans of both the show and Kroi are encouraged to engage with the new content and anticipate the upcoming tour. Tickets for Kroi’s “JUNGLE” tour are available on a first-come, first-served basis, reflecting the band’s rising prominence in Japan’s contemporary music scene.

Kroi’s ongoing commitment to artistic growth and collaboration, exemplified through their cross-genre sound and partnerships with notable musicians and directors, positions them as a significant force in the intersection of anime and music culture. Their contribution to LIAR GAME’s second season not only continues a tradition of impactful anime theme songs but also broadens their reach to international audiences who follow the series.
