Sasuke Shinden: Book of Sunrise
During the attack on the Bamboo Village by exploding humans, Chino and the others had the women and children take shelter. After Sasuke Uchiha subdued the attackers, Chino went to the shelter to see if Amino was safe. The people within the shelter, however, came flooding out as Amino, now an exploding human, walked out. Amino took a knife and stabbed herself in the neck, causing her body to explode.
