Ch. 81The limitations of Shikkotsu Forest's Sage Mode
Key plot points and events
- Uchiha Yi compares Hashirama’s apparently effortless Sage Mode with the more demanding methods used by Naruto and Kabuto, which increases his curiosity about Shikkotsu Forest’s version.
- Katsuyu explains that teaching Yi will require absorbing about 100 milliliters of his blood each time he trains. Yi worries about the cost, while Kushina warns that repeated blood loss will limit how often he can practice.
- Despite the difficulty, Yi agrees to train. He can already sense natural energy, but needs Katsuyu’s guidance to balance it with his physical and spiritual energies. He also hopes to use the training as a foundation for creating a Sage Mode better suited to humans.
- Yi asks Kushina to bring him food while he trains and has Katsuyu summon him to Shikkotsu Forest. He appears there before the enormous slug.
- Back with the others, Nawaki feels discouraged by Yi’s progress. Kushina encourages him not to compare himself to Yi and warns him to be less careless; Hyuga Rinka simply returns to training.
Character developments and interactions
- Uchiha Yi is ambitious but practical: he questions the physical cost of training, yet accepts it because of Sage Mode’s potential and his goal of adapting it for humans.
- Katsuyu acts as Yi’s instructor and explains the demands of her Sage Mode. Their arrangement is presented as mutually beneficial.
- Kushina supports Yi by volunteering to bring food. She also shows concern for Nawaki, using teasing to remind him to be careful.
- Nawaki is impressed and frustrated by the widening gap between himself and Yi, but accepts Kushina’s encouragement.
- Hyuga Rinka remains reserved toward Nawaki and responds to Yi’s departure by focusing on her own training.
Significant themes
- Ambition and sacrifice: Greater strength requires physical costs, preparation, and persistence.
- Individual limits and adaptation: Sage techniques developed by animal summons may not suit humans, prompting Yi to seek a human-adapted form.
- Comparison and self-improvement: Kushina urges Nawaki to measure progress against his past self rather than Yi.
- Carelessness and survival: Training is not enough; attention to practical dangers can be just as important.
