Rinu
Rinu (Japanese: 莉犬, born 24 May 1998) is a Japanese singer, voice actor, and internet performer. He is a member of the entertainment group Strawberry Prince, commonly abbreviated as Sutopuri, in which he is associated with the color red and a dog-eared illustrated persona. His work combines recorded popular music with livestreaming, animation, voice performance, and concerts mediated through digital character imagery.
Rinu’s career developed within the Japanese utaite tradition, a form of internet-based vocal performance centered on recordings distributed through video-sharing platforms. Utaite performers initially became known through interpretations of existing songs, particularly compositions associated with Vocaloid, before an increasing number moved into original recording, commercial publishing, and large-scale live entertainment. Rinu’s transition followed this broader pattern while retaining the illustrated identity and direct audience communication characteristic of the form.
Career
Rinu began publishing vocal recordings online during the 2010s. His early output included cover versions, short dramatic performances, and conversational broadcasts, which established a consistent relationship between his singing voice and his illustrated canine motif. The name 莉犬 combines the character 莉, frequently encountered in Japanese personal names, with 犬, meaning “dog.” Its pronunciation, Rīnu, also functions as a compact stage name suitable for written captions, spoken introductions, and platform identifiers.
In 2016, Rinu became one of the principal members of Strawberry Prince alongside Nanamori, Jel, Satomi, Colon, and Root. The group consolidated several activities that had previously been distributed across individual internet channels. These included recorded singing, livestreamed conversation, comedy-oriented audio drama, and performances presented through illustrated avatars.
The organization of Strawberry Prince differs from that of a conventional vocal group because each member maintains an individual online identity while participating in collective productions. Rinu’s solo recordings therefore continued alongside group releases and concert appearances. His vocal presentation generally employs a high register and compressed phrasing derived from online cover-song culture, while his spoken performances make greater use of character dialogue and rapid changes in intonation.
Rinu released his first full-length solo album, Time Capsule, in December 2019. The album combined original songs with material connected to his established internet repertoire and reached the upper positions of the Japanese Oricon Albums Chart. Its production placed the voice at the center of densely arranged electronic and rock instrumentation, preserving the direct vocal emphasis of utaite recordings within a commercial album format.
His second album, Shutter Chance!, followed in January 2022. The photographic terminology of its title corresponded with an album concept organized around memory, performance, and the controlled presentation of personal experience. The release also reflected the increasing integration of Rinu’s solo career with the distribution and concert infrastructure developed for Strawberry Prince.
During the group’s 2022 dome-concert period, programs credited vocal performances to Rinu, Satomi, Colon, Root, Jel, and You Watanabe. Their appearances used alternating solo passages and ensemble sections rather than a fixed lead-vocal arrangement. Rinu’s contribution remained continuous with his established group role, particularly in passages that connected prerecorded character dialogue with live singing.
Performance identity
Rinu’s public representation is divided between his physical stage presence and an illustrated red-haired character with canine ears. This arrangement does not function as complete anonymity, because live appearances and documentary material have incorporated the performer’s physical body. Instead, the character provides a stable visual form across recordings, merchandise, animation, and broadcasts whose production circumstances vary substantially.
The use of a persistent illustrated persona connects Rinu to virtual YouTubers, although his practice emerged from utaite performance and does not depend on continuous real-time avatar animation. It also differs from conventional stage costuming because the same design can appear independently in music videos, static promotional images, and voiced narrative sequences. The persona consequently operates as a shared visual reference rather than as a single technical mode of performance.
In 2017, Rinu publicly identified himself as a man and described having been assigned female at birth. This disclosure became part of his autobiographical work and informed later discussions of voice, embodiment, and self-representation in his recordings. His illustrated identity remained visually consistent across this period, allowing biographical disclosure to coexist with the established conventions of character-mediated performance.
Music and voice work
Rinu’s solo music draws primarily from Japanese pop rock, electronic popular music, and the compositional practices associated with online song producers. Melodic lines frequently occupy the upper part of his range, while arrangements alternate between rhythmically dense verses and choruses designed around sustained melodic phrases. This construction accommodates both the close-microphone sound of internet recordings and the projected delivery required by concert performance.
His voice acting extends the same vocal identity into scripted dialogue. Rather than forming a wholly separate professional practice, this work is integrated with animated videos and dramatic material distributed through the channels of Strawberry Prince. The resulting productions place songs, spoken narrative, and recurring character designs within a common media framework.
Rinu’s recorded persona therefore illustrates a broader change in Japanese popular entertainment during the late 2010s and early 2020s. Internet performers increasingly moved between independently distributed recordings and institutionally organized concerts without abandoning the visual conventions through which their original audiences recognized them. In Rinu’s case, the dog motif, color designation, and characteristic vocal register provide continuity across those environments.
