Sawai's art style is a mix of very blocky-looking characters and, sometimes, very detailed art. He tends to focus on the realistic appearance of his characters' facial expressions when they freak out. Because of the nature of his series, he has often written Bo-bobo version parodies of other authors' manga, including Akira Toriyama's "Dragon Ball", Yudetamago's "Kinnikuman", Kazuki Takahashi's "Yu-Gi-Oh!", and Tsugumi Ohba's and Takeshi Obata's "Death Note". He was also the leader of a team of gag-based manga artists (alongside Kyosuke Usuta, Amon Dai and Kouji Ooishi) who wrote a special 30th anniversary chapter of Osamu Akimoto's "Kochira Katsushika-ku Kameari Kōen-mae Hashutsujo".
