Kikoru’s Unprecedented Compatibility with Numbers Weapons
Chapter 124 opens with a flashback that likely harks back to the Compatible User Arc, highlighting Gen Narumi’s astonished reaction to Kikoru’s remarkable compatibility levels.

Her request to keep this discovery confidential highlights her tactical thinking and determination to minimize risk.
Training and Strategic Insights
Following this, Kikoru asks Narumi to train her in effectively wielding Weapon No. 1.
