The two people that Asta wanted Finral to go and get were Kaito and Kahono from the Seabed Temple. As it he was able to get bottom of the Witch Queen's magic and leave the Witch's Forest with it. Realizing what he was thinking as both siblings were amongst those hurt the most after Asta during their fight with Vetto. Kaito lost a leg and Kahono had her throat damaged. Those injuries were serious but not as serious as Asta who had both arms broken and then cursed on top of that.
When he arrived in the Seabed Temple in a manner where he just did not seem to appear randomly. As Spatial Magic was easy magic to misuse after all and everyone would just a person to just appear in their home all of sudden. So he appears at the entrance of the Seabed Temple and rushed when they realized it was a member of the Black Bulls that arrived.
"You can teleport to where ever you been before, right," Kaito asked him being shocking quickly for someone with only of his original one leg left.
"As long I have been there at least once before" Finral answered him.
"Than you can take me the Clover Kingdom Capital than right," he asked him
"Wait how did you know I was even coming here for that," the Spatial Magic user asked.
He was not sure if Asta had come here before himself but that would not have made sense as they went straight to the Witch's Forest after Vanessa. So he just assumed he would have told them why he was here and keep what he was assume was suppose to be a surprise for them both.
"Kahono has gone missing as she was last seen talking to apparently a shadowy cloaked mage. Though I got a message from her recently saying she was going to see Asta" he told him
'This shadowy cloaked mage seems suspicious but if they had done anything to Kahono. Why would she be able to send a message claiming she was going to see Asta' Finral thought.
Not having enough information to go off of and even if they were suspicious. It was not like he could fight them himself as he thought about trying to making more offensive based spells. That was still in the planning staging and Kaito did only have one leg at the moment with the other being a pegleg.
"I will take you to the Asta but first get your leg if you still have it," Finral asked.
Though it seemed like a weird request to make of someone, Kaito did as he had it preserved in water magic. Someone might be able to use magic restore to him thus better to keep it around as what if that method to restore his leg actually required his original one. Rather than just growing a new one to replace it. Though he also brought his sword along just in case as well as he might not be able to fight as his peek at the moment but that did not mean he could fight at all.
Unaware that there would be more than one shocking surprise waiting for him there. Though Finral was also unaware that there would be a surprise for him awaiting him when he got back to the Clover Kingdom as well.
