At Drytan's base he set off a powerful bomb trap, Kurenai Zero was forced to retreat and rearrange plans to avoid casualties like in the battle with Olympus.
When they arrived at Kurenai Zero's headquarters, they were surprised to see that Kai had returned and welcomed them "Welcome, friends." Kai said in a happy tone, then they were all grateful that you were back and the ones who brought you were Tristan Tritan and Tirtan.
At Black Shadow headquarters, Olympus was angry because Drytan let Kurenai Zero retreat and rearranged their plans, after that Drtan came and apologized, Olympus forgave him, after that they both went to prison to see Kai's condition, when they arrived there they surprised to see that Kai's prison door was broken and Kai was no longer there.
"Damn it, you little bug dares to take my little toy." Olympus said in an evil tone, he was getting annoyed because of that and was going to wage war against Kurenai Zero.
Meanwhile in the spirit forest, Kai invited the spirits to work together, and also invited 9 legendary monsters to help him. After meeting the holy spirit of the upper moon, Kai negotiated with the help of Revis and Kuraeza. He managed to negotiate and cooperate with the holy spirit of the upper moon named Ygird Elyre.
Arriving at Kurenai Zero's emergency headquarters which was under a small hut near the forest, they made an attack plan to avenge all those who died in the war against Black Shadow, before making their plan to bring the bodies of all the fallen students and Kurenai Zero members into the room. UKS at the academy.
They planned to train for today and think about their plans for tomorrow, this time they got a new skill called Curse of Darkness, this skill emits a terrible aura that makes people who are not mentally strong feel afraid or hesitant about fainting.
"With this new skill I can fight Olympus." Kai said with burning enthusiasm.
They still have to face the big challenges and obstacles that face them. They don't know that there will be a big war that is being planned by Black Shadow.
