rensouhou-chan
連装砲ちゃん (lit. "Twin-gun turret-chan")
Shimakaze's familiar-like sidekicks in Kantai Collection. It originated from Shimakaze's three twin 12.7 cm/50 naval gun turrets. One of them is using an lifebuoy with the word "ぜかまし" ("Zekamashi", "Shimakaze" reversed) on them.
Amatsukaze also has one which she calls "Rensouhou-kun". Its difference compared to Shimakaze's own is that it is encased in a ship-like hull and it has rounder facial features compared to them.
Akizuki also has two of those based on her own four twin 10cm/65 naval guns. They are named "Chou-10cm-hou-chan".
