With the transition from the quarter-finals to the semi-finals, Blader Gai announces the four Bladers left in Neo Battle Bladers. Consisting of Shinobu Hiryūin, Kira Hayama, Sakyo Kuroyami, and Zero Kurogane. Subsequently, he details the two battles that will compromise the semi-finals that will later lead to the finals and declare the winner of the tournament. The two battles will consist of Zero versing Sakyo with the second as Shinobu versing Kira. As the audience is loud in its cheering of its competitors, Tsubasa and Madoka are still concerned with DNA. Mal even shows them footage of some of the semi-finals battles via her laptop, trying to comfort them in their DNA scruples. As the evening shifts to nighttime, Shinobu has come to Bey Park along with some friends in order to undergo extensive training prior to his fight with Kira. At first he is fighting Ren as her Thief Phoenic battles Shinobi Saramanda. Shinobu is able to quickly unleash multiples of Saramanda and follow it up with a special move that he first used when defeating Yoshio in the quarter-finals. The Saramandas circled and trapped Phoenic as each Saramanda transformed into a ring of fire that was able to blow Phoenic out of the BeyStadium and much to her dismay. Meanwhile, Zero decides to partake some training for himself elsewhere outside of Metal Bey City. Bringing Benkei along, Zero returns to the same area where he first had his battle with Sakyo. He had Benkei bring a wrecking ball crane with him, that is to be used for Zero to counter and defeat. Although Benkei is very skeptical of this, not wanting to endanger Zero's life or put any hurt on him, Zero commands Benkei to go through with it, to which the former does, despite his dismay. As Zero launches out Samurai Ifraid into the ginormous hole mimicking a Stadium, Benkei controls the wrecking ball to circle the hole at its edge. When Ifraid collides with the wrecking ball, it is thrown back immediately which also throws its owner back as well. Zero does not care and stands up once more to launch Ifraid at the wrecking ball, this time intending to hold it back. While Ifraid does manage to hold the wrecking ball for a short period, it cannot hold much longer as it throws Ifraid back again. With every collision and failure that causes Zero to be hardly thrown to the ground in hurt, Zero comes back for another chance at trial-and-error to defeat the wrecking ball. Back at the Bey Park, Kite tells Ren to step aside and give himself a chance at defeating Shinobu. Raised by the platform to the Zero-G Stadium, Kite launches Guardian Revizer to test Saramanda's offensive skills. When the Beys are launched, they immediately deliver the opponent with a barrage of hits and smashes. Kite gives a short speech to Shinobu, telling him that he must defeat Kira in Neo Battle Bladers and advance to the finals at all costs. Knowing how powerful Kira truly is by experience, Kite orders Shinobu to do what he must do and defeat Kira Hayama. Shinobu, moved by the words of his friend, accepts this and acknowledges what it will mean to defeat Kira. Elsewhere at the DNA headquarters, Yoshio is the middle of a battle with Kira. Commanding his Bandid Goreim to deliver Berserker Begirados with one smash, as Goreim does this it is suddenly ricocheted out of the BeyStadium with no movement by Begirados. Yoshio, saddened by his lost, gives Genjūrō a turn. As Kira is as calm in his battles, Genjūrō launches Bandid Genbull to collide with Begirados but Genjūrō obtains the same result that Yoshio did. Surprised by this, he then gives a turn to Spike and his Thief Girago. Intending to barrage Begirados with a marathon of clashes, Spike launches Girago but also faces the same result. Shocked by this, he lets Captain Arrow have a chance at combating Begirados. Launching out Archer Wyvang, Arrow immediately unleashes a tornado that stands atop of Wyvang, while simultaneously using Tornado Attack to attack Begirados. Flattered by Arrow's dogged practice, Kira chuckles when Berserker Begirados offers no movement at all and still manages to throw back the opposing Beyblade, in the form of Wyvang. Shocked and feeling what his comrades have, Ian Garcia commands the DNA Bladers, expect Yoshio and Kira to leave, and they gladly do so. Kira then exits the Zero-G Stadium to hold his Berserker Begirados and have a short reminiscing with it. He remember his three, other opponent in the semi-finals, Shinobu, Sakyo and Zero. Each using a ring of fire Special Move that defeated Yoshio, an easy attack that defeated Arrow and the Burning Upper that defeated Takanosuke, respectively. A little concerned for how powerful the others are, Merci interrupts Kira's time to himself to announce that the "dark energy" collected by Begirados is now complete and there is no need to use it, anymore. Surprised by this, Kira drops his former Beyblade to the floor, leaving Berserker Begirados. Yoshio approaches Kira as he watched what Kira has done, asking is he is sure to leave Begirados and Kira accepts this as the two walk to the soon-to-commence Neo Battle Bladers. Selen and Argo even exchange a short discussion about Beserker Begirados, as although Selen believed Kira should have kept Begirados, Argo dismisses it because Kira will have obtained a "new Beyblade" even more powerful than the one before and that it will most likely be the most powerful Beyblade that the world have ever known. Finally, the semi-finalists of Neo Battle Bladers have all arrived and are now ready to proceed in their battles. With the audience of the whole tournament cheering loudly in delight, Gai announces that Zero and Sakyo shall battle first. Subsequently, Zero and Sakyo enter the Zero-G platforms and make way for their Zero-G battle. Zero and Sakyo are about to partake in their second battle, ever as Zero is very dogged to defeat Sakyo following his intensive training, while Sakyo plans to do the same.
