1 Person and 1 Person (１人と１人, 1-ri to 1-ri) is the 8th chapter of Clockwork Planet manga series.
The gang arrive inside the core tower to find the Meister Guild attempting to fix the gravitational anomaly themselves. Marie introduces the team to their secret weapon, Naoto, who meanwhile admires the inner clockwork of the tower. Naoto observes the faults in the mechanism through his sense of hearing and pinpoints 18 defects.
