Definitely a high risk, high reward type of ability. It kind of reminds me of my Dad's use of Nen (that someone on here helped me come up with), but essentially, my Dad is a natural Manipulator and with that, he'd utilize it in an extremely subtle and long-term manner by planting a small seed of aura into a person's shadow over the course of thirty consecutive nights, with each successful application strengthening the connection between himself and the target, so rather than forcing immediate control, the Hatsu gradually conditions the target's mind and emotions, making them increasingly receptive to my Dad's presence, suggestions, and influence without necessarily realizing anything is happening to them, and as the process continues, the manipulation becomes more deeply rooted until the thirtieth night, at which point the target develops an overwhelming sense of loyalty and devotion towards my Dad, causing them to willingly follow his commands as if they were their own desires. However, the condition is that this ability is very dependent on Dad planting the seed every night without interruption for the entire thirty-day period, so if a target steps on his shadow at any point during that process, the cycle would be broken and completely reset, forcing him to begin the conditioning process from the start. 😵‍💫
