Dance Covers and Cosplay Performances of Ano Natsu ga Houwa Suru

The emotional power of Kanzaki Iori’s masterpiece, "那个夏日已然饱和" (Ano Natsu ga Houwa Suru), extends far beyond its original music and novel. In the ACG dance cover (宅舞) and cosplay community, this track has become a popular foundation for highly dramatic, narrative-driven stage and video performances.

If you are looking to explore the choreography, cosplay crossovers, and performance styles of this trend, here is an overview of how creators are bringing this heartbreaking summer story to life.

The Choreography Blueprint: Kakumi & JIO

While some dancers opt for entirely original choreographies or explore alternative tracks from the same album (such as the song "正体"), the most widely covered and celebrated version is the choreography created by Kakumi & JIO.

This routine is known for its intense physical expression and emotional weight, capturing the tragic, desperate tone of the song. It serves as the standard base for most performance videos and live convention stages.

The Vocaloid Cosplay Standard and Fandom Crossovers

The emotional narrative of the song naturally lends itself to twin-themed and narrative-focused cosplays.

• Kagamine Rin & Len: This is the most dominant cosplay theme for the dance. Dancers frequently perform as the iconic Vocaloid twins, utilizing their visual chemistry to elevate the dramatic and emotional weight of the performance.
• Creative Crossovers: The dance has also been adapted to other fandoms. For instance:
  • shuca (Shu & Luca): Inspired by the Nijisanji EN fanwork "酷暑将至", creators have adapted the Kakumi & JIO choreography to represent this pairing, bringing a unique narrative layer to the dance.
  • Yehliu Kei (叶流圭): Performers have adapted the song and dance to represent the character from the series Oblivion Battery (忘却battery), showcasing the song's versatility in portraying complex character dynamics.

The Emotional Impact on Stage

Performances of "那个夏日已然饱和" are notorious for being tear-jerkers. Dancers frequently report being deeply moved during rehearsals and live shows. Stage performances at conventions—such as the Changsha Mengka anime convention—have left both live audiences and the performers themselves in tears. The intense physical storytelling and raw emotion make it a highlight of any ACG stage lineup.

Practical Tips and Caveats for Performers

For those looking to record or perform this choreography, experienced community creators share several valuable lessons:

Category	Key Considerations & Tips
Physical Safety	The intense, high-energy movements—which often involve falling or dramatic floor work—can easily lead to minor physical injuries, such as scraped skin or falls. Dancers are advised to practice safely.
Creative Props	Using visual props, such as "spider silk," can significantly enhance the dramatic tension of the performance when handled with proper technique.
Outdoor Filming	Outdoor recordings frequently face unpredictable weather and pedestrian disruptions, leading to multiple NGs and potential frame mismatches during camera transitions.
Stage Technicalities	For live stage performances, coordinate carefully with the venue's tech crew, as there is a risk of audio-video desynchronization with background screen projections.
Post-Production	Investing time in detailed post-production color grading and editing is highly recommended to elevate the final mood and visual polish of your video.
