The Tale of Derek and the Hidden Sand Chapter 75

Xiaonan seemed to be instantly back to that stormy evening, and his grandmother, the only person he depended on, had passed away.

Later, when he was alone and hungry and cold, Yahiko extended a helping hand to him.

Since then, in Konan's mind, Yahiko has been like an older brother.

Despite the occasional unreliable situations, the two managed to survive by doing odd jobs in the town and occasionally stealing some food and other daily necessities at the flea market.

Later, with the joining of Nagato, Konan felt like she had another younger brother.
