Sakawa

Sakawa (酒匂) was the last of four Agano-class light cruisers built for the Imperial Japanese Navy (IJN) during World War II. Fuel shortages crippled the IJN's operations by the time the ship was completed in late 1944 and she never left Japanese waters. After the war, Sakawa was used to ferry Japanese troops home until she was selected in early 1946 to be expended for nuclear weapon tests during Operation Crossroads. The ship was used as a target during the first bomb test on 1 July and sank the following day.

Appearance
She had a light-purple short hair.

Line
She's making a pun with her verbal tic 'ぴゃっ' and the word 'ぴゃっと' which is a slang for 'moving quickly'.

Trivia
While at Eniwetok, five of its American sailors were angry over the dismal working conditions aboard Sakawa. In a ship normally staffed by over 730 men, the U.S. Navy used a crew of 165 doing the work of 325. The five sailors sabotaged the ship by removing the pressure line to the over-speed trip valves in the fuel system and pouring sand into the oil and water pumps. They smashed gauges, tachometers, and cut high pressure steam lines in an attempt to get relieved of duty aboard the filthy warship. Rather than being relieved of duty, the five sailors were brought up on charges. In May, after emergency repairs, Sakawa reached Bikini Atoll.
