|“||My name is Tenryuu. Fufufu, ya scared?||„|
Tenryuu has short purple hair and yellow eyes. She wears a school uniform with a necktie and thighhighs and an eyepatch over her left eye. Her weapon is a sword.
Depicted with a tough girl personality with the catchphrase of "Heh, you scared?"; she is, however, often depicted in a way that subverts this. She is also depicted as a babysitter to the Akatsuki class.
- A common theme where Tenryuu and her destroyers escort was regularly used in expeditions due to her low fuel and ammo cost. The official 4-koma also showed Tenryuu as being good at taking care of children (destroyers), hence the name.
- Sunk by USS Albacore (SS-218) off Madang, New Guinea.
- A character from Touken Ranbu (another DMM-hosted game), Shokudaikiri Mitsutada, greatly resembles her.
