I have two ideas and wanted to make a vote, you can decide if I implement it.
First, I want to the mc become good friends with Uchiha Madara. They will then play around with the ninja world and later kill the Otsusukis together.
For example, they won't tell Obito that the Infinite Tsukuyomi plan is a scam and then watch him as he frees Kaguya and Mc will take Kaguya as a love interest/kill her (depends on the vote)
Become friends with Madara
Kaguya becomes the lover of the mc
The second idea is that the mc gets a dimensional chat group (1. option - villain chat group, where he kind of becomes the mentor of the villains and they abuse the protagonists of their worlds together) (2. option - chat group is the normal type where they fight against transmigrators etc. together) and after that travels to different worlds. You know the drill.
Mc gets a chat group
Villain chat group (abuse MCs together)
Normal chatgroup fight against transmigrators etc.
Nagato was stunned when he saw Uchiha Madara's words and then reacted.
[Uzumaki Nagato: Uchiha Madara, what do you mean by taking back your eyes? Are you trying say that my Rinnegan eyes are yours? Impossible, I have had them since childhood!]
[Uchiha Madara: Hahaha Nagato boy, I transplanted them to you when you were a child, because my body was already dying of old age and your task was to resurrect me. But now I am already alive, so I will take them back.
I am informing you so that you can try to resist, I have high expectations for you.
Let's dance Nagato boy, show me how far you developed my eyes Hahahaha]
Madara was feeling excited because of his young body and decided to play a little game with Nagato so that he can have a bit of fun dancing.
After he used Izanagi to survive the battle with Hashirama, he stayed alone in a dark cave all the time. For someone like him, this is simply torture, but for his grand plan, for world peace he endured the humiliation and loneliness.
Now that he regained his youth and the success of Infinite Tsukuyomi is not far away, he is in a very good mood.
[Senju Hashirama: Madara! Don't make trouble, wait for me to be resurrected, then we can dance together if you want.]
[Terumi Mei: Dancing together? It's a bit unexpected for me that the legendary Uchiha Madara has such an interest.]
[Uzumaki Mito: Yes! Hashirama you bastard, not once did you try to talk to me, but only chat with Madara. Am I not important to you? It's always Madara this, Madara that. Even when we were alive, you were like this. I want a divorce!]
Uzumaki Mito was already almost crying when she saw that her beloved Hashirama ignoring her for so long. She wanted him to take the initiative, but he just started talking about dancing with Madara again.
[Senju Hashirama: Wife listen to me! No divorce okay, I love you. Okay? I won't talk to Madara again, I promise.]
[Senju Tsunade: Grandpa! YOU ARE IGNORING ME TOO! DO YOU KNOW WHAT THE BASTARDS SARUTOBI HIRUZEN AND DANZO DID TO ME?? THEY KILLED EVERYONE AHHHH! I AM THE ONLY SENJU LEFT, EVEN MY LITTLE BROTHER NAWAKI! WHEN I FOUND HIM ALL HIS ORGANS WERE HOLLOWED OUT! THEY CALCULATED EVERYONE TO DEATH AND DID HUMAN EXPERIMENTS WITH THEM! I WILL KILL THEM ALL!]
Everyone was shocked when they saw Tsunade's outburst. But then, the ones that saw the question found it normal.
After all, Tsunade is really miserable having her whole clan, brother and lover killed by her own teacher.
Tobirama exploded immediately.
[Senju Tobirama: IS THIS TRUE? HOW CAN IT BE?! I GAVE MY LIFE TO PROTECT THEM, HOW CAN THEY DO SUCH A THING?]
Uchiha Takashi saw the opportunity and immediately added oil to the fire.
[Uchiha Takashi: It is indeed true. The first question from the stone tablet was about this topic.]
[Senju Nawaki: Don't be sad sister, I am fine now. Maybe I can answer a question correctly and resurrect. I miss you sister.]
[Senju Tsunade: Nawaki?! I miss you so much... Wait for me Nawaki I will give everything to resurrect you and I will get revenge for you!]
Sarutobi Hiruzen and Danzo who were already scared since the moment of Tsunade's outburst, almost fainted in anger when they saw Uchiha Takashi throwing them under the bus.
[Senju Tobirama: What have I done? I accepted these beasts as disciples. It's all my fault.
@Uchiha Takashi, listen to me. If you agree to torture and kill these bastards, I will pass on all my ninjutsu to you. If you want you can be Hokage or you can destroy Konoha directly. Konoha without Senju might as well not exist.]
The initial self-blame and regret in Tobiramas mind disappeared, replaced with extreme ruthlessness. He was originally an extremely decisive and ruthless man, how can he let emotions cloud his judgment. Now he will do his best to get revenge for the things his disciples did.
He has already decided, he will pass on his whole legacy to the person who kills his disgusting disciples. He doesn't even care about Konoha anymore, they can all go to hell.
[Senju Hashirama: Tsuna, you suffered my little granddaughter. Tobirama! What kind of disciples have you accepted? Even passing on Konoha to them?
I also agree with killing them, although I can't pass on my Mokuton ninjutsu, whoever kills them, can be Hokage.
@Uchiha Takashi Please do not destroy Konoha, the villagers and normal ninjas are innocent. Don't make an unnecessary blood-bath please.]
Even the good-natured Hashirama was extremely angry. He cannot imagine how much his favourite granddaughter suffered all these years.
[Uchiha Takashi: I have a personal feud with them too. So don't worry, I will kill them, but I am neither interested in the Hokage position, nor in destroying Konoha.
But I don't want to kill them yet, the things they have done over the years are much more than that. I want the stone tablet to announce their sins through the questions, then I will kill them.]
Takashi was not interested in being Hokage at all, he had seen Boruto before he transmigrated.
Naruto was so busy as Hokage, that even with his almost god-like endurance he fainted multiple times because of exhaustion.
He neglected his family for years, even letting a shadow clone attend his daughter's birthday.
Takashi would never agree to do this kind of work and in the end strength is the root of everything.
Having power will erode the spirit of the strong for most people, making them obsessed with it.
Takashi does not want to tempt himself with this kind of thing, it's better to answer questions, get stronger and enjoy life to it's fullest.
