Understanding Edo Tensei and Chakra Absorption in the World of Naruto

In the grand narrative of the Naruto series, Edo Tensei or the Reincarnation Technique plays a pivotal role in the battle dynamics. This technique allows reanimated shinobis to battle with limitless chakra reserves, which leads to the question: can one with a chakra absorption ability achieve the same by using Edo Tensei targets? Let's delve into the mechanics and explore the possibilities.

The Reality of Edo Tensei

Edo Tensei reanimates the deceased shinobis and grants them chakra reserves that fill up faster than living shinobis. However, this does not equate to infinite chakra reserves. For instance, in the case of Minato Namikaze, even though he had the chakra of Hashirama and absorbed Sage Mode chakra, he still ran out of chakra. This clearly indicates that the reanimated shinobis do not have true infinite chakra reserves. Every shinobi, even those reanimated by Edo Tensei, face the eventual depletion of chakra, which necessitates rest for recovery.

The Limitations of Chakra Absorption via Edo Tensei

Directly absorbing chakra from the reanimated targets' bodies would result in the disintegration of the jutsu, as seen in certain instances. This limitation means that chakra must be absorbed indirectly. One workaround is to have the targets continuously perform jutsus, which the Rinnegan user can then absorb. While this concept introduces an intriguing plot hole, it remains unverified in the manga. However, this method could theoretically enable the absorption of chakra without disintegration.

Chakra Absorption Benefits and Challenges

Even with the theoretical ability to absorb chakra, the process remains exhausting for the body. Additionally, excessive chakra can be detrimental to one's health. Therefore, even if a shinobi with chakra-absorption abilities could temporarily boost their reserves, there are limits to how much chakra they can absorb and process without risking health issues. The key factor is the source of the chakra: the shinobi's body, which has limits similar to any other shinobi.

The only confirmed cases of chakra absorption in the series are characters with the Rinnegan or those connected to the Otsutsuki clan. For instance, Madara Uchiha began to break down as he absorbed Hashirama Senju's chakra, highlighting the risks involved in such practices. Sasuke Uchiha, with access to the Nine-tailed Beast's power, still required significant rest after powerful attacks. This further underscores the limitations of chakra absorption.

Conclusion and Takeaways

In conclusion, while the concept of absorbing chakra from an Edo Tensei target introduces an intriguing theoretical possibility, the practical implementation remains fraught with limitations. Direct absorption is not feasible, and indirect absorption requires continuous jutsu usage, which is highly tiring for both the absorber and the target. Thus, achieving infinite chakra through this method is not realistically possible in the Naruto universe. The strength and effectiveness of any such ability would depend on the source of the chakra, the absorber's proficiency, and the risks involved.
