Watch this legendary scene that demonstrates the show's over-the-top animation style and fan service:
The manga was left unfinished at volume 7 following the death of writer Daisuke Satō in 2017. The illustrator, Shōji Satō, chose not to continue the story out of respect for his partner.
The series is a well-known example of the ecchi genre, frequently using physics-defying animation and "bullet-time" slow motion for suggestive scenes.
