Fight! Kotori-Tank! (戦え!ことりタンク! Tatakae! Kotori Tanku!) is a magical/machine girl (advertised as "Battle Girl") series created by Cure Alumi.


A few years ago, a little girl bought a bow, but it was not an ordinary purchase, as one would normally expect. The MakiFuku company dubbed the bow as the Lucky Fresh Bow, created to where only one was to bestow incredible power to its customer. The little girl happened to be that customer. Plagued with sleepless nights with nightmares involving aliens and destruction, there was nothing she could do about it. That is, until now.
Now in high school, Sakamoto Amaya still keeps this bow dear to her, despite the pressure put onto her. Her dreams have ended long ago, although they seem to become reality. It is not long until one last dream comes to her: press the bow and shout "Ready! Initiate Change!" When she finally stumbles across the aliens from her childhood dreams, she finally stands up and performs the action.
And with that action, the battle girl Kotori-Tank is born. With a "Target Lock-On!", she is prepared to defend her ground.



Sakamoto Amaya (坂本雨夜 Sakamoto Amaya)
Amaya is, to put it brief, not much of fighting material. She often panics over even the smallest of situations and takes all of it too seriously. She ends up becoming a bit too pessimistic as a result, and feels unsure of herself most of the time. Sometimes she can easily be mistaken for a tomboy, based on her clothing choice, but she happens to be a lot more girly than people think. She doesn't mind if she grabs people's attention, even if not intended, and can be much of an extrovert. She has the ability to transform into the battle girl Kotori-Tank (ことりタンク Kotori Tanku).


The antagonist group, the Millennium Knights (千年騎士 Chitose kishi), are four human-like aliens who have the ability to grow in size, at their own will, up to 20 feet. Because of their size, all four prove as a great threat to Earth, and plan to turn it into a "heaven" for their race, after previous attempts have resulted in failure. They consist of the following:

  • Ryuga (リュガ Ryuga), the self-proclaimed leader who isn't afraid to make the first move.
  • Stella (ステラ Sutera), the strategist who happens to be a little worried about her abilities.
  • Andro (アンドロ Andoro), the most silent of the group, but can make surprise attacks with ease.
  • Aurora (オーロラ Ōrora), the protector who can produce a protective aura under certain circumstances.


Kousaka Nobuo (高坂信夫 Kōsaka Nobuo)
A nerdy boy who seems to have caught the attention of only Amaya.

Yashima Seiya (八嶋星矢 Yashima Seiya)
The current president of MakiFuku and the co-creator of the Lucky Fresh Bow.


Lucky Fresh Bow (ラッキーフレッシュボー Rakkī Furesshu Bō)
The name of the bow, created by the accessories company MakiFuku, that Amaya had bought when younger. Though many were sold, only one bestowed incredible power, hence the name. As that lucky customer, Amaya simply can press her fingers onto the middle of the bow and use the phrase "Ready! Initiate Change!" to transform.


Amanogawa (天ノ川 Amanogawa)
A city in Japan where Amaya lives and the center of the series. Its space-related name caught the attention of the antagonists, leading them to believe this could be their chance to make room for them to settle.

Amanogawa District High School (天ノ川地区高校 Amanogawa Chiku Kōkō)
The official high school of Amanogawa and where Amaya attends as a 2nd year.

MakiFuku (まきふく MakiFuku)
An accessories store located in several places across the district, named after the company of the same name. This is where Amaya first bought the Lucky Fresh Bow when she was little. It is said that the people who run it created the bow for a reason.
