Reason

"What's happening here, Grandpa?" Tsunade asks.

"Well.... How can I explain this..... Actually, every single one of the patriarchs of the Clan left a trace of our own Chakra to every badge that's why I'm here."

"So that's why."

"I also left my chakra on your pendant in case your life is in danger but it seems you never got a dangerous moment so it will not activate."

"As for the reason why we left our own Chakra to the badge is to see if the contract will going to complete in the end."

"After all, what we did is a huge gamble, even though we know that we scam Brother Lou some of us don't trust him at all that's why we did this," Hashirama explains.

"And also, Tobirama comes up with this plan to teach the future generation what they need to do to accept our inheritance, but it seems you fail."

Lou smiles gently." Tobirama is really cautious, he did not trust me even though I give him ideas numerous times."

"Hehehe~ sorry about that Brother Lou," Hashirama sheepish smile.

"Well never mind, let's continue." Lou starts to activate all the badge resulting in every first patriarch of the Clan appearing.

Lou explains everything to them to prevent trouble and hustle, but from their appearance, it seems they understand that they fail in their plan.

"Ha~ so my clan is really failed me, I even prepared numerous ninjitsu just for them."

"Hey Hyuga Clan Head, you're too much, even if you fail your clan is the richest, look at my clan, only a single girl left." Yūhi Clan Head said.

"Mine only left a boy with the dead fish eye, at least it's about but from my understanding towards this boy look it seems my Clan will perish in his hand." Hatake Clan Head helpless said.

"Hahaha! Mine is fine, look at those huge bodies, I'm pretty sure my clan is fine."

"Sorry, First Hokage, it seems my Grandson fail your expectations, I can sense that there's numerous blood on my clan but they are weak."

The Sarutobi Clan Head looks at the Third Hokage." I don't know what you did but at least if you want to push my clan into number one, at least prepare and not like this."

"I can see the wisdom in your eyes, you are more like a politician than a Village Leader for me but at least you plan everything before doing it."

"As long as I see, your success but at the same time you made the whole village in danger, you can bluff as long as you live but do you realize what will happen if this information goes out of your hand?"

"... I'm... I'm sorry ancestor."

The Clan Head of Uchiha looks at Danzo and ask." Are you part of my Clan?"

Danzo's lips twitch and said." No."

"Then why do you have my Grandson Sharingan? And also in your arm, you have dozen of my Clan eyes?"

Hashirama also asks." I feel my Wood Style on you but I know you are not part of my clan, tell me, who are you and how did you get that?"

All of them look at Danzo, Lou's face turn playful when the two clan head asked.

"This..." Hachizen doesn't know what to say, he wants to defend Danzo but he knows that the thing he has right now comes from the dirty mean.

"I also feel huge malice from those eyes, it means that the owner of those eyes died in a tragic way."

"I'm... I'm from Shimura Clan, leader of the root... I did this to protect Konoha Village." Danzo gloomy said.

".... I can sense a huge hostile and racist from you, do you despite my clan?" Uchiha Clan Head asks.

"And if you're doing this for Konoha, tell me then how do you use Sharingan? Did you master our illusion technique?"

Lou chuckled and said." He using Sharingan as disposable tools."

"Shut up!" Danzo angry shout.

"You see, he masters Izanagi for the purpose of saving his life."
