Because Hinata had a crush on Naruto, she often followed behind him. After she learned that Naruto had acknowledged Xiao Xie as his big brother, she had also gone to Xiao Xie's Department Store to buy some things, so she knew him as well.
"So it's little Hinata! I didn't expect to run into you here. I was out purchasing some goods and happened to pass by. Then I heard the sounds of fighting here and came over to take a look. When I found out they were Konoha ninja, I stepped in to help."
Xiao Xie put on a look of having just noticed Hinata, reached out to ruffle her hair, and explained with a smile.
"Hinata, do you know this big brother?" Inuzuka Kiba asked curiously.
Yuhi Kurenai and Aburame Shino also looked at Hinata with curious expressions after hearing Kiba's question.
"Big Brother Xiao Xie owns the Department Store in the village, but I didn't know he was this powerful!" Hinata glanced up at Xiao Xie. Only after seeing that he did not seem bothered did she softly answer Kiba and the others.
"A big brother like him is just a shop owner in the village? That's hard to believe when he's so strong!" Kiba cried out in surprise.
"Woof!"
Akamaru, lying atop Kiba's head, also barked in agreement.
Seeing Yuhi Kurenai and the others staring at him in confusion, Xiao Xie rubbed Hinata's little head and smiled. "I like a peaceful, stable life. I only helped you this time because I didn't want to see you die for nothing. Please keep what happened today a secret, all right?"
After speaking, Xiao Xie ignored Yuhi Kurenai and the others' reactions. He turned, picked up the Executioner's Blade, and used the Instantaneous Technique to vanish before their eyes.
