非公認戦隊アキバレンジャー
如今的秋叶原正被《超级战队系列》和《二次元新娘学园Z-Cune葵》两大作品平分人气，以两部作品的人物为基础，战队咖啡厅秘密基地的店长叶加濑博世开发出新英雄的装备。 其后，叶加濑将Z-Cune葵外型的手办变身器交给三名持有“妄想力”的男女，让他们组成非公认战队秋叶原连者，阻止邪团法人密商乙的阴谋。
Visiting the Secret Base for the first time in nine months, Nobuo and Hiroyo recollect what happened during the previous battle... but their memories aren’t quite right...
Discovering Akibaranger has become official at the cost of Dairanger, Nobuo tries to fix matters by himself, but he must ultimately reteam with Yumeria and an idol wannabe to deal with the new threat to reality.
As the Akibarangers try and figure out how they’ve replaced Dairanger as the 17th Super Sentai, they are attacked by an angry Kibaranger, who declares he’s now only a shadow of his former self, when suddenly, Malshina appears!
Dealing with Luna quitting the team, Akagi learns that Yumeria got married during their time away from their life as the Unofficial Sentai, but her mother-in-law’s anti-otaku feelings create trouble for her. When Malsheena uses her own version of the Z-Cune to transform, and a monster spoils the Z-Cune Aoi film, it’s up to Yumeria to inspire Akagi’s delusions on a whole new level, but can they dodge the mother-in-law?!
Luna’s misunderstanding causes a twisted delusion where Super Sentai is an adaptation of America’s popular Powerful Rangers franchise! With the Red and Green Powerful Rangers teaming up with Malsheena against the Akibarangers and their “knockoff” Super Sentai, could this be the end of the Super Sentai franchise forever?!
After General Pain creates a new mascot character that exploits Akagi’s weakness for super smooth shiny robotic girls, the Akibarangers are swiftly defeated and the effects leak into the real world! Can they find a way to train Akagi to overcome his weakness and defeat the latest threat to reality?!
General Pain creates a 3rd Goraiger who steals the justice-loving hearts of the other two Goraigers and turns them to evil! Thanks to Malshina’s meddling, reality now features three extra days in the week, and otaku activities are outlawed!
General Pain unleashes a reconfigured Tentoraiger, Mutou Mushiten, who uses the powers of past Sentai villains. As the Akibarangers try and figure out how to beat their new enemy, they find themselves face to face with veteran villain suit actor Okamoto Yoshinori!
Having found General Pain’s hideout, the Akibarangers fall into his trap and are Delusimported into a Grand Delusion where General Pain makes the rules! As they struggle to find a way out, they realize that they are experiencing another franchise trope: the defeat of the team’s mecha!
Withe General Pain seemingly trapped in his own Grand Delusion, things go somewhat back to normal, but Malshina talks General Pain into creating a new Alpaca Section Chief to eliminate the Akibarangers!
The Akibarangers confront Malshina, who has remodeled the entire reality to become the star of her own franchise in place of the Super Sentai! As the Akibarangers lose their will to fight, will Malshina’s new reality stand?!
After defeating Delu Knight by exploiting the defeat flags in the warped reality, a strange new hero appears to become the 4th member of the Akibaranger team! However, upon their return to Secret Base Cafe, things are still twisted as they discover their new teammate is intended to replace the Super Sentai franchise entirely! The grand final battle is about to begin!
As the final battle has come to a close, the memories come flowing back as Kozkoz and Hakase remember their friends’ adventures, but what is the future of the Unofficial Sentai?
