Chapter 555 was a great chapter in many ways, I expected something like that to end the third raikage, but i was getting super worried when the bjuu bomb failed but not surprising right. Naruto didnt finsh his training, he did leave in a hurry.
But I can without a doubt now say that kishi has showed us the real reason why edo tensei was devised and the big downfall in using edo tensei incorrectly like orocihmaru/kabuto.
In the recent chapter the third raikage stabbed himself via a rasengan. Basiclly Kabuto didnt know about the hazzards in the thrid raikage's fighting style. But the raikage knows the risks all too well and if he were in control he would have retracted the attack at the last second because of his previos near death blunder from his eigth tails fight. Kabuto didnt even make him use black lightning and the third riakage developed the technique.
So we can conclude when we see edo tensei summons fight, so much really depends on the summoner. Another case of this is with the 1st and 2nd hokages. They are revered to be very powerful , yet we didnt see much from either of the them as edo tensei summons. For example, 2nd hokage was skilled in time-space jutsu(according to minato), 1st hokage, well we dont alot but we know hes very strong to take on madara(ems) and the fox.
So the only way to get the best results when using edo tensei is not to take complete control and let the summon fight with its own will. But this is hard as usally this jutsu has been used in akward situations where the summons are fighting their own allies like the 1st&2nd hokages against the 3rd hokage and therefore orocihmaru took complete control and as a result we saw limited skills. Another big case of this was Hanzo's fight with the samari leader, kabuto didnt try to take control of Hanzo until it was too late. This is one of my biggest disapointments we will never see this shinobi fight again and when we did see him it was brief but I understand why it went down the way it did. Hanzo iniatlly wanted to fight and we got to see more skillls he can excute but ultimately Hanzo lost his modivation to fight and killed himself in the end and again like the hokage fight we didnt see much from Hanzo abilites wise.
So to overcome this, the situation has to match the head to head encounter meaning pit the summons against their natural enemy. For example lets setup this hypotheical situation. Madara killed hasihrama during their fight and to avenge his death his brother the 2nd hokage summons him and kills madara. Now hasihrama would want to fight madara and would be fighting with his knowledge of his own powers and the oppenent.(Something that has been kabuto's undoing in these past fights, obviosly third raikage recently but nagato last battle and a few other fights. Kabuto underestimated the situation despite knowing Nagato was paralysed. Nagato set up many safegaurds to aviod fighting directly himself when he was alive.)
Which comes to my main point of this thread, why did the 2nd hokage create edo tensei? Dispite the senju clan are described as peace keepers, playing with the dead doesnt seem their style at all.
So I believe the 2nd hokage created this jutsu for two reasons.
- To have closure with someone dead, you know the famous phrase, " let their soul rest in peace". And as we saw early in the war once a soul(not taken over by the summoner) is at peace they return to the afterlife.
- And Second, simular to the first but nothing to do with the summoner personally but a common enemy, particulay where there's bad blood already. Eg..madara and hasihrama,itachi and madara,muu and 2nd muzikage etc..
- Here's another idea(http://www.mangashare.com/forums/thr...636#post895636) to combat the tailed beasts. After hasihrama's passing and distribution of the tailed beasts to balance the powers it would be a good idea to have this technique to contain the tailed beasts. Many sacrifces have been made to just to be hosts so I can see this happening.
Despite these nobal causes, this does require a living sacrifice. The era for the 2nd hokage to devise this I assume was during the same era of madara and hasihrama(both hasihrama and madara know about this jutsu already). Which was an era of constant war between clans, times must have been dire at times and shinobi were willing do anything to protect their clan's survival even sacifice themselves(uchiha did plenty of this for MS and Izanagi). As a result I believe the 2nd hokage declared this jutsu forbidden after hasihrama united clans to form villages.
Hope you enjoyed my take on a yet simple detail from chapter 555 but I think it does prove edo tensei real purpose, and the creator's mindset to think of something like this radical jutsu.
