The princess who's been held captive by the Demon Lord's army is scheduled to be executed by the Demon Lord's relentless torture!

One year after the events of Beyblade Burst Rise, brothers Hikaru, and Hyuga witness the power of superking/sparking evolutions of Valtryek, Roktavor, and Satomb. The three beys radiate a power that was not even dreamable, due to their bladers pulling off a sparking launch. Hyuga and Hikaru get inspired to make their own sparking beys, Hyperion and Helios, and compete with the legendary bladers, training to best the top ranked bladers to ever touch the stadium. Prepared to do whatever it takes to become the best, they head across the globe to challenge the best to ever let it rip, in an effort to become stronger, and battle all of the top bladers that were able to make their mark in the stadium.

Shungo Ninomiya is just an ordinary, run-of-the-mill high school student who lives at home with his older sister Ryoko—at least when she's not away doing her job as a mercenary. However, Shungo's life ceases to be normal the moment a cute girl named Mayu Tsukimura descends into the middle of his school's campus in a military-grade helicopter. It turns out Ryoko sent this girl, along with her older brother Mikihiro, to live at the Ninomiya household. But the newly-arrived siblings are a little special: Mayu is, in fact, a succubus and her brother, an incubus! And as if the circumstances are not problematic enough, Mayu is crippled with androphobia—the fear of men—and it's up to Shungo to help her overcome this at the behest of his sister. Ryoko plans to force Mayu to be closer to Shungo, and to do this, she’ll employ some questionable methods such as having them share the same bed and even take baths together. The situation further complicates when student council president Reika Houjou arrives as the new maid of the Ninomiya family, and she will stop at nothing to thwart Shungo and Mayu’s sexually-geared training. With the sudden arrival of all these oddities, Shungo's ordinary life is about to be thrown into utter turmoil. [Written by MAL Rewrite]
