# Perfect And Ultimate Getter

> Perfect And Ultimate Getter is a 2023 mashup meme where Yoasobi's "IDOL" and JAM Project's "STORM" share nearly identical chorus progressions, spawning viral crossover videos and fan art across Japanese social media.

Perfect and Ultimate Getter (君は完璧で究極のゲッター) is a 2023 mashup meme built on the discovery that Yoasobi's "IDOL," the opening theme for the anime Oshi no Ko, and JAM Project's "STORM," the opening theme for the 2000 OVA Shin Getter Robo vs Neo Getter Robo, share nearly identical chorus progressions[1]. The viral mashup videos that combined these two songs sparked a wave of crossover parodies and fan art across Japanese social media, while reviving chart interest in a 23-year-old mecha anime theme song[2].

## Origin
On April 12, 2023, the Japanese pop music duo Yoasobi (consisting of producer Ayase and vocalist Ikura) published the official music video for "IDOL" on YouTube and Niconico[3]. The song served as the opening theme for the Spring 2023 anime adaptation of Oshi no Ko. Meanwhile, "STORM" had been recorded over two decades earlier by anison supergroup JAM Project, founded in 2000 by veteran singer Ichirou Mizuki[5], as the opening theme for Shin Getter Robo vs Neo Getter Robo, a four-episode OVA released between December 2000 and June 2001[7].

Viewers on Niconico and social media quickly noticed the structural similarity between the two songs' choruses[4]. On April 19, 2023, Twitter user @9LOAtu47Ey7sI6s (輝², "teruteru") uploaded the first mashup video combining the two songs[4]. One week later, on April 26, Niconico user Gerbera Zwiebel uploaded their own version to the video platform[4]. The Twitter video by teruteru earned over 330,000 retweets and 660,000 likes while being played more than 1.2 million times within its first two weeks[4].

## Overview
The meme centers on a 30-second mashup that splices together the chorus of "IDOL" by Yoasobi and "STORM" by JAM Project[4]. Both songs share a similar build-up during their respective choruses, making the transition between them almost seamless with only a minor tempo adjustment needed[1]. The name "Perfect and Ultimate Getter" (完璧で究極のゲッター, Kanpeki de Kyūkyoku no Gettā) comes from mashing together the lyrics of both choruses, combining Oshi no Ko's idol-themed lyrics with Getter Robo's mecha battle imagery[4].

The absurd contrast between an idol anime and a super robot show is a big part of the joke, though fans quickly pointed out the two series actually share some thematic DNA. Both Oshi no Ko and the Getter Robo saga feature dark, intense storylines, and the protagonist of Getter Robo Arc is driven by revenge for his mother, mirroring the motivations of Oshi no Ko's Aqua[2] (translated from Japanese).

## How It Spread
The viral mashup videos opened the floodgates for follow-up content across multiple platforms. Crossover parodies, fan illustrations, and additional mashups with other songs spread rapidly on Twitter, Niconico, Nico Nico Seiga, Pixiv, and YouTube[4]. On Niconico specifically, the phrase "Perfect and Ultimate Getter" began appearing as a comment swarm, with viewers flooding Oshi no Ko episodes and the official "IDOL" music video with "Getter!" comments whenever the chorus approached[2] (translated from Japanese).

On May 4, 2023, the official Yoasobi Twitter account acknowledged the trend by retweeting a video from the Nikufes outdoor music event, where crowds were dancing to the mashup. The retweet included a robot emoji[4]. The "Ultimate Getter" phrase also trended on Twitter in Japan during this period[2] (translated from Japanese).

The meme had a measurable effect on music sales. On May 8, 2023, "STORM 2021," JAM Project's self-cover version of the original song, appeared on Spotify Japan's Viral Top 50 chart[2] (translated from Japanese). By May 23, the original "STORM" hit number one on the Oricon Music Store's daily singles download ranking, an extraordinary result for a song released more than 20 years prior[2] (translated from Japanese). It held the top spot on the weekly ranking for May 24-30 as well[2]. On the other side of the mashup, "IDOL" by Yoasobi reached number one on the Billboard Global Excl. US chart on June 6, 2023, becoming the first Japanese act to top that chart, and held the number-one spot on Billboard Japan's Hot 100 for eight consecutive weeks[3].

Online commentators noted that the mashup's popularity aligned with the in-universe concept of "Getter Rays," a fictional cosmic radiation in the Getter Robo franchise that absorbs and fuses everything it touches. Fans joked that the meme itself was proof of Getter Rays at work, pulling unrelated anime properties into Getter Robo's orbit[4].

The meme also built on an existing Niconico tradition. A parody video series called "Changing into XX while None Realizes It" (全く気付かないうちに○○になるシリーズ), active since early 2014, had established the format of seamlessly splicing two songs together at a similar musical passage[4]. The most successful prior example was "Zenryoku☆Shangri-La!," which mashed together angela's "Shangri-La" from Fafner in the Azure and "Zenryoku☆Summer!" from Aho-Girl[8]. That mashup's top video hit over 3 million plays in its first six months, and angela eventually performed the mashup at their own concerts[4].

## How to Use
The core format involves combining footage or audio from "IDOL" and "STORM" at the chorus, where the two songs' melodies converge. Creators typically:
1. Play "IDOL" through its verse and build-up
2. At the chorus, cut to "STORM" (or vice versa), adjusting the tempo slightly to smooth the transition
3. Match the video footage to the audio, often splicing Oshi no Ko animation with Shin Getter Robo vs Neo Getter Robo clips

## Cultural Impact
The meme gave Shin Getter Robo vs Neo Getter Robo, a cult-classic OVA that many Western fans had barely heard of, a significant visibility boost. The blogger behind Ogiue Maniax wrote that while Getter Robo is "just part of the bedrock of anime and the mecha genre," they had "always assumed Shin vs. Neo was just known in the little corner of the fandom I had occupied"[1]. The trend brought new viewers to the OVA and drove measurable chart movement for a song from the year 2000[2].

The timing carried a bittersweet note. Ichirou Mizuki, one of the lead vocalists on the original "STORM" and the founder of JAM Project, had passed away on December 6, 2022, from lung cancer[5]. Fans and commentators speculated that Mizuki would have embraced the meme, pointing to JAM Project's history of performing fan-made mashups, including their cover of "Okkusenman"[1]. Hironobu Kageyama and the rest of JAM Project's active roster were still performing as of 2023[1].

On TV Tropes, the meme was noted as a potential case of "Adaptation Displacement" for the Getter Robo franchise, with Shin Getter vs Neo Getter "shaping up to be" better known internationally thanks to the mashup than through its own original release[6].

## Fun Facts
- The entire mashup works within roughly 30 seconds of audio, yet that brief overlap was enough to drive a 20-year-old song to number one on download charts[2].
- Fans connected the meme to Getter Robo lore by invoking "Getter Rays," the fictional cosmic energy in the franchise that absorbs everything in its path, joking that the meme proved Getter Rays were real and had consumed Oshi no Ko[4].
- The "Zenryoku☆Shangri-La!" mashup, a spiritual predecessor on Niconico, was eventually performed live by angela, the original artist of both component songs, at their concerts in the late 2010s[4].
- JAM Project, who performed "STORM," had a long history of engaging with fan content, including covering the Niconico viral hit "Okkusenman"[1].
- Pixiv Encyclopedia's article on the meme includes an extensive list of thematic parallels between Oshi no Ko and Getter Robo, including shared plot motifs of revenge, maternal loss, and transformation[2].
