Boruto Uzumaki's helpless plea in Chapter 25 reveals a startling truth about his training future. The young shinobi's proposal for assistance from his greatest enemy signals the end of conventional mentorship and the beginning of something remarkable. Traditional teachers like Sasuke and Kashin Koji have reached their limits, leaving only one being capable of unlocking the protagonist's true potential.
Momoshiki Otsutsuki arises as the most rational choice for Boruto's next instructor, despite their violent history. The Karma seal's secrets can only be solved by its original creator, and no earthly master has the knowledge needed to harness its full power. This twisted mentorship arrangement alters from necessity into opportunity.

Throughout the series, mentorship has played a vital role in shaping young shinobi. Sasuke Uchiha did serve as Boruto's main instructor, teaching him refined combat techniques, strategic thinking, and the art of swordsmanship. The legendary Uchiha imparted everything from jutsu mastery to survival skills.
After Sasuke's unfortunate transformation, Kashin Koji stepped in to fill the mentorship void. Under Koji's tutelage, the young Uzumaki learned advanced techniques in a relatively short time. His training contained learning abilities from his future self via prescience.
Momoshiki's Potential as an Instructor of Boruto

The climactic moments of Chapter 25 portray Boruto making the phenomenal decision to seek Momoshiki's assistance, surrendering his body in exchange for the power needed to defeat Jura. This frantic gamble could transform their relationship from one of mutual hatred to unexpected cooperation.
Momoshiki has unparalleled knowledge of Karma's true potential. The Otsutsuki's understanding of chakra manipulation, dimensional abilities, and advanced jutsu could feed the young ninja with skills no earthly teacher could offer.
Beyond raw power, Momoshiki exemplifies exceptional analytical abilities and vast knowledge of his clan's history and techniques. This philosophic depth could help the protagonist of the series understand not just how to use these abilities, but when and why to utilize them strategically.
A Partnership Born Out of Necessity

The current threat posed by Jura and the Shinju Clones has created possibilities that demand unusual solutions. Jura symbolizes a danger that could potentially destroy everything they've worked toward.
The evolving dynamic between the protagonist and Momoshiki has deviated from morally antagonistic to somewhat cooperative in recent chapters. This gradual change suggests that joint benefits, rather than forced cooperation, might boost their potential partnership.
Under Momoshiki's direction, Boruto could master advanced techniques, including chakra absorption, redirection, and enhanced Karma control. These skills would prove valuable against opponents like Jura. Such training would advance him beyond the level of previous-generation shinobi, conditioning him for threats that surpass anything the ninja world has yet faced.
This possible mentorship pact would fundamentally alter the series' trajectory. Rather than obeying standard shinobi training methods, Boruto would be learning from an alien outlook that views power and combat differently than human instructors.
The relationship would also test the young ninja's character in distinctive ways. Learning from someone who once strived to destroy him would need maturity and wisdom beyond his years. Success would deliver growth not just in power, but in understanding and forgiveness.
