Yasushi Kamasaki (Japanese: 鎌先 (かまさき) 靖志 (やすし) Kamasaki Yasushi) is the former vice-captain of the Date Tech High volleyball club. In 2021, he works as a furniture upholsterer[1].


He has sandy blonde hair that may have been dyed, judging from his dark sideburns and eyebrows. He has a large muscular build and is often seen scowling or yelling at someone (particularly, Futakuchi Kenji).


He is loud and strict and takes the game seriously. He often argues with and threatens Futakuchi Kenji, a problematic junior who doesn't show much respect for his seniors. He is quite competitive and belligerent: when he saw Karasuno at the Spring High, he gave them the middle finger and made a face without holding back at all.


Interhigh Arc

Kamasaki took part in the game between Date Tech and Karasuno. During the game, he and Futakuchi would at times argue and have to be kept apart by Aone at Moniwa's request. After Date Tech lost, Kamasaki and the other third years retired from the team.

Spring High Preliminary Arc

Kamasaki and the other third years enter the gymnasium in a rush to see if their former teammates are winning and winces when he sees that Aoba Johsai had already won the first set. Wanting to see how the new team was coming along, Kamasaki notices that Koganegawa is still a beginner and has a lot to learn. When Futakuchi is visibly worn out due to having to care for the team, Kamasaki finds himself amused at the fact that Futakuchi, who has become the new team captain, is having trouble handling the new team. Near the end of the match, Kamasaki yells in delight as Futakuchi scores. When Futakuchi manages a snide remark when seeing the third years after losing the match, Kamasaki yells at his junior. After this, Kamasaki tells Koganegawa that he ’sucks’ and Koganegawa apologizes loudly. Additionally, he tells Futakuchi to be grateful to have had Moniwa as captain in the past now that he has to be one. Afterward, he would advise the team of how they could continue to grow stronger and he would also agree to help with practices.

Tokyo Nationals Arc

Kamasaki, Moniwa, and Sasaya would sneak into Date Tech's gym (Karasuno in the anime) to watch the practice match between Date Tech and Karasuno. He is mostly seen cheering for the team from the balcony area and occasionally hackling Futakuchi for any mishaps or how he acts as the new team captain. After the match, he would wish the Karasuno third years good luck at Nationals and offhandedly mention how he might grow facial hair; possibly from thinking that Asahi came off as intimidating due to having facial hair.

Final Arc

In the coverage of events after Nationals, Kamasaki is with Moniwa and Sasaya in the audience when Date Tech wins the Interhigh tournament[2]. As of 2021, Kamasaki works as an upholsterer in Miyagi.
