He quickly overpowers Yamato and Cobalt Blaster begins to experience problems. Just as things seem to turn for the worse, Akyulus comes in and hands Yamato a new strike shot "Use it" are his last words, as he passes out... Yamato receives the Strike shot, but not without shedding tears.
Mie, Armada and Liena decide to take Yamato and the gang go for a picnic to relax before the final match. Yamato seems uneasy now that the entire B-da world is resting on his shoulders. Grey challenges Yamato to a friendly match, which Yamato easily wins, later on Terry challenges him, and then Wen, Lee and Kiba. After defeating everybody, Akyulus challenges Yamato and the battle ends in a draw. Yamato realizes that he doesn't need to carry all he burden since his family and every friend are supporting him and have helped him to get this far and vows to win. That night however, Akyulus has a nightmare in which Galdezer defeats Yamato with the Gaedaeum shot. He wakes up and decides to use the last remain of his B-da spirit to create an ultimate strike shot that will fight par on par with the Ultimate Evil Strike shot, despite Shin's many warnings that doing so could mean his death.
On the competition Yamato’s team has 1 Victory and 2 Losses, one more loss would result in handing the B-da world to Bedeus. Grey decides to fight on the 4th round against the Aztec Mask, in a 3 point Direct Battle on the Hurricane stage. At the beginning, Grey experiences difficulties as the stage wind pressure blows away his B-daballs, Aztec mask on the other hand who focuses on power has no problems on getting through. Grey struggles as he is barely able to dodge, until Bull arrives and with a power up for Chrome Harrier, is able to fight on equal footing. Bedeus realizes to have underestimated Grey, and increases the Wind pressure of the Hurricane stage to its maximum, rendering Chrome Harrier's improved cyclone attacks to be useless. Aztec Mask gets the upper hand once more and with absolute attack power blasts Grey to near defeat. In the last moment sensing his friends feelings, Grey uses all his B-da spirit and summons the wind to fight on his side! The soldier of the gale creates a giant Cyclone and with god-like speed, strikes down Aztec mask and seizes victory! The score is now tied 2 to 2, Grey passes the final task to Yamato who awaits for the Final Battle that will decide the fate of the entire B-da World.
Now back at full potential, Akyulus decides to battle on the next match. The 3rd battle is Akyulus vs Equus on the circular canon stage, but this time Equus seems to operate his B-daman with an advanced brainstorm system which controls the B-daman using his brainwaves. When the battle begins, Akyulus faces problems with the advanced use of the brainstorm and it seems like no b-daplayer can keep up with the speed of the brainstorm, besides it seems to have serious side-effects for the user. Equus begins to suffer the strains from Brainstorm and almost starts to get out of control. Akyulus manages to keep up with the brainstorm system and is able to barely fight at equal footing, but in the end he decides to achieve a long-term victory by using his Stealth shot to miss on purpose and instead of earning his last point to win the match, he attacks the core system of Brainstorm. Equus however is able to land his final point and Akyulus loses the match. Akyulus is upset on having lost such an important match, but knows that by disabling brainstorm it will give Grey and Yamato a better chance to win the following matches.
The matches are in a tie 1 to 1. Although Ferreus won against Terry, B-daeus punishes her. Equus tries to stop him but is forced to test a new machine instead. Meanwhile, Yamato and his gang are busy training for the next match, but Akyulys emotional damage is still too deep to allow him to fight at full power. Gunnos and others argue that Akyulus is not ready and they should battle to decide who is entitled for the 3rd match. Jinbee shows up and guides the gang to the place for the battle but they are ambushed by B-Deus' members. Outnumberd by B-Deus, they are driven up to the wall but Gunnos and others protect Akyulus, throwing themselves into the battle. To respond them, Akyulys finally makes a stunning comeback!
The second match is about to start. From team Fire Spirits, Terry steps in to fight, on the other hand despite Equus claims Bedeus (Master Hefai) chooses Ferreus to battle instead. The second match takes place on the Devil canyon where there lies a bottomless buttom, were falling would meant an instant loss. The battle ensues and Terry seems to have serious disadvantage. At the end Terry decides not to give up and fights till the end, giving inspiration to his team mates and specially Akyulus. Unfortunately Terry loses the match.
The Air tightens as the First of the Decisive battles is about to start. The team to get 3 victories wins the 5 VS 5 matches. The 1st Round, The Pillar Destruction battle, the first to go on Yamato’s Team is Enjyu, while Boss master sends out Hajiya. Enjyu easily overpowers Haijya and destroys most of his pillars in the beginning of the match. Just before he’s about to win, Haijya reveals to have Kia kidnapped as a hostage linked to his final pillar. If Enjyu were to destroy it Kia would fall and die. Variable Kaiser’s attacks are sealed and Haijya begins to get the upper hand near to winning. Kia shouts in the middle of the crisis and knocks some sense back into Enjyu, just in time for him to use his Black Drive Shot. Enjyu defeats Haijya, and catches Kia as he falls.
