The story is good and the MC system is also somewhat power balanced. The only problem is the author seems to boost Konoha too much. With that kind of efficiency and combat teamwork, Akatsuki will be obliterated before they could reach Shippuden which is so absurd. There is also this overpowered Yamanaka jutsu who could completely read other memories like computer's scanning in matter of days and it could be done any Yamanaka clan shinobi which is more ridiculous. I remember they need at least a few months before they could recover a complete memory from Amegakure shinobi during the Pain attack and it is done by the Yamanaka Clan head. Moreover, they only recover superficial recent memory and not those long memory. The Konoha also seems to not lack of manpower that shown in the manga. In the manga, they are shown that their iwagakure front is completely collapse and only hold alone by Minato. Yet, they still capable to spare a lot of shinobi to resist Kirigakure full force attack before their own commander appeared. Last, Jiraiya in this story simply overpowered. Without enter sage mode, he could release taijutsu strong enough to kill any shinobi with single punch and in fast speed. With this kind of power Jiraiya could fight Pain without even relying sage mode.
It is good but there are part that heavily bother me. The author create a non-canon Vice Admiral who somehow has enough strength to beat two or three ordinary Vice Admiral in the future. Although he is not as strong as the three logia admiral, he is still very strong. And it is quite bothering me about his power and rank. To make it worse, Bege got heavily nerf at this moment. It is like reading a child fighting an adult which left more negative impression.
At first, it was good with all the detailed lore and stuff with the main story. Then, the MC chooses to gamble, risking getting the infamous Voldemort of the DADA curse rather than facing his sealed memories just because he wants to speed up the investigation. To make things worse, the author and the MC knew the power of knowing the main plot, yet they decided not to accept it. His character becomes pretty timid and stupid after coming to Hogwarts, which makes his previous brilliant impression as a 'golden viper' gone.
I don't know if the author stopped in the middle of writing and forgot his initial plot or something else, but the MC is pretty inconsistent. It would be pretty believable if he were somehow controlled by the old Dumbledore rather than making all these stupid decisions.
