Also known as: 長10cm砲ちゃん, ちょうじゅっせんちほうちゃん
The twin familiar-like sidekicks of Akizuki, who appear similar to Shimakaze's own Rensouhou-Chan trio. They're modeled after the Akizuki-class destroyers' four twin long 10cm gun Type 98 mounts.
They appear as gun turrets with :3, cylindric torsos, and small "metal flipper" limbs.
In the official CG, they are slotted into the split-bow configuration of Akizuki's Rigging .
The chou-10cm-hou-chan are a trait shared with the rest of the Akizuki-class. As such, Teruzuki, Suzutsuki and Hatsuzuki have their own pair with their own perks. (Chou-10cm-Hou-Chan (Teruzuki'S), Chou-10cm-Hou-Chan (Suzutsuki'S) and Chou-10cm-Hou-Chan (Hatsuzuki'S))
