Cain hurriedly explained, but judging by Arania's doubtful expression, she did not seem to believe him.
By then, Kagura had already composed herself and said to Arania in front of her, "Big Sister Arania, Big Brother didn't bully me."
Only then did Arania lower her guard and apologize to Cain. "Sorry, I got anxious when I saw Kagura crying."
Cain waved it off to show he did not mind. At that moment, Kagura spoke up. "Big Brother, can you take me to see that red-haired sister?"
"I want to thank her in person, and I also want to know more about my brother."
Hearing that Kagura wanted to see Erza, Cain did not agree right away. Instead, he looked at Arania, since this woman seemed to be Kagura's guardian.
From Cain's earlier explanation, Arania understood that the red-haired girl was Kagura's savior.
Normally, it was only right to thank one's savior in person, but she was currently carrying out a job. It would not be good to simply abandon it.
Just as Arania was caught in a dilemma, Cain suddenly thought of something. "If it's inconvenient for you right now, I can take Kagura there."
"I'll bring her back afterward. Oh, and I'm a mage from Fairy Tail."
As he spoke, Cain showed the guild mark on his right arm.
Once Arania saw that he was a mage from Fairy Tail, she could not help but relax. "You should've said you were from Fairy Tail earlier. Then I'll leave Kagura to you. Make sure to bring her back to Mermaid Heel afterward."
Cain nodded with a smile and agreed.
Arania then turned around and left, continuing with her job.
The reason Arania's attitude changed so quickly was that Fairy Tail could be considered a major guild compared to Mermaid Heel.
