Ch. 21A "Trouble" Warning After Dark
After Shuo warned the outpost leaders about likely infiltration tactics, Minato strengthened the night defenses and assigned Shuo to the southeastern watchtower. Shuo detected two approaching groups, triggering the alarm as Minato and the others moved to intercept them, and the battle began.
- Minato and the outpost leaders analyzed Shuo's map of suspicious ninja movements, and Shuo suggested the enemy might attack before dawn after scouting the outpost and blocking nearby roads.
- Shuo advised tightening security and waiting for the infiltrators to approach, so Minato doubled the sentries, increased patrols, and prepared mobile squads.
- Minato assigned Shuo to the southeastern watchtower, where Shuo used Light Perception to detect two stealthy groups moving toward the outpost.
- Shuo alerted the watchtower Chunin, who sounded the alarm, and Minato ordered squads to intercept the attackers while Kakashi and Obito flanked them and Rin prepared the medical team.
- Minato's forces surged into the darkness, and the first ninjutsu collision marked the start of the battle.
