Ikki Kurogane and Ascarid vs Big Baby

Ikki Kurogane and Iris Acarid vs Big Baby is a fight between the Hagun Academy student Ikki Kurogane and the 4th ranked KOK A-League competitor Iris Ascarid against All-Goal's ally Big Baby. It takes place during the Battle of Kardia.

Prologue
As the Vermillion Army fights the Cradleland soldiers controlled by All-Goal, they use a tactic created by Ikki, freeing multiple soldiers with the help of Tilmitt and Miriallia. Ikki, Tilmitt and Miriallia are in a helicopter, when they are attacked by a 30 meter tall giant, who crushes their helicopter. Ikki, Tilmitt and Miriallia manage to escape, while the giant, who is an ally of All-Goal called Big Baby, easily kills multiple soldiers of the Vermillion. Tilmitt and Miriallia don't believe that they will be able to defeat Big Baby, but Ikki rushes in to fight the giant, despite having no magic power left, from previously using Ittou Rasetsu.

Battle
Ikki uses his Device, to cut the base of a nearby water hydrant, the water pressure causing it to launch upwards, with Ikki riding on top of it. As he gets closer to Big Baby, Ikki attacks him with his first secret sword technique Saigeki, to pierce Big Baby's eye.

Big Baby though is simply annoyed by this, launching Ikki away with his backhand. When Ikki hits the ground, he deliberately rolls on the ground, managing to not lose his consciousness. Ikki does still break multiple of his bones, making him unable to get back up. As Big Baby runs towards Ikki, he id suddenly electrocuted by high-voltage wires on the railroads. This has been Ikki's aim from the start. Despite getting badly electrocuted, Big Baby survives, using his ability to increase his size to 300 meters.

Big Baby attempts to crush Ikki under his foot, as Ikki is unable to move due to his injuries. Ascarid though saves Ikki, stopping Big Baby's foot, with just her halberd. Ascarid then removes her helmet, and harshly tells Big Baby to cut it out, as if reprimanding a child. Big Baby then starts crying, and runs away.

Epilogue
After the fight, Ascarid explains to Ikki, that Big Baby is just a five year old child, who was recruited by Rebellion, until leaving with All-Goal. Ascarid and Ikki then notice that forces from the League of Mage-Knight Nations have arrived to help Vermillion.
