As Goku and the group entered Babel the Saiyan ignored all protocol running ahead without a word. Dodging all the attendants trying to stop them, however in vain as the Saiyan leapt and dodged them all until coming to the main entrance to the dungeon.
A large ten meter in diameter shaft was placed perfectly at the center of the basement of Babel. A long line of rope used as an elevator to get Adventurers in and out of the dungeon. Without a care for how deep it was Goku leapt down without hesitation his body quickly disappearing from the sight of the pursuers that Goku wasn't able to shake off easily.
Aiz and Bete were shocked at the sight of someone leaping into the dungeon for the first time. "THAT SPIKEY HAIRED IDIOT!" Bete yelled. After being so easily blind sided by Goku he refused to be shown up again, and like the man before him immediately leapt down with Aiz following him.
Aiz who wasn't as beaten up as Bete, and had a calmer mind was smart enough to cast her wind magic allowing both herself and Bete to maintain a speed close to that of Goku's descent. His feet scratching and scraping against the walls seemed to help him stay at a non-lethal speed as he descended.
As they neared the floor a bit of fear overcame the Sword Princess as Goku didn't slow. She hadn't casted her magic on Goku she wasn't even sure if she could considering it only worked on Bete's magical equipment, however the fear turned to surprise as Goku in the last moment kicked off the wall and sped down the cavern of the first floor whilst Aiz and Bete followed soon after. The pair in equal disbelief as he took off like a rocket into the first floor of the dungeon without hesitation.
