(To not confuse a reader, i need to flashback what really happen in this two years. There will be around 3-4 chapter before main arc)
Back to two years earlier.
After Setsuna graduated, he wanted to return and attend a high-level Konoha meeting. But then he noticed his teacher, Senju Shiro, try to divert his attention with a mission. Every time they finish a mission, they will get another mission.
This situation lasted until three months later, when he noticed his teacher trying to prevent him from participating in the Konoha meeting.
When he went to meet the elder and patriarch of the Uchiha clan, he found out every rule that Senju Tobirama had proposed.
He found out there are many laws that squeezed out Uchiha. At first, under Setsuna ideology, Uchiha integration with Konoha has run smoothly. But one and a half years later, Uchiha has become estranged from Konoha.
Then he noticed many of those ideas were suggested by Tobirama Senju, and now he found out he had been trapped by him. No wonder his teacher is from Senju, because they wanted to make sure he didn't participate in any of the meetings.
After that, he tried to attend the next meeting, but once again, Senju Shiro gave him a mission. Because of this situation, he then used Shadow Clone to run a mission and then sneak into a meeting. At the age of 15 years old, Setsuna is very strong, and no one can defeat him except Hashirama, Madara, and Izuna.
This level D mission is as easy as breathing, so a normal shadow clone can handle it well. When Setsuna participates in the meeting, Tobirama's face becomes ugly. Because he wanted to suggest a police force for Konoha.
Before this, he limits Uchiha to Konoha Hospital. He gives his reason that by allowing Uchiha to work in Konoha Hospital, it will stagnate medical ninja progress. By allowing other clans to join, such as the Aburame clan, they can create an antidote to poisoning. Aburame are good with poison insects, so they can create antidotes with them. So, before this, Konoha Hospital had more than 60% of Uchiha, now there is only 10% left.
Tobirama has fought with Uchiha for so many years, the reason he didn't want any Uchiha to work there was to prevent them from awakening Sharingan. He knows that by touching their emotions, they can awaken Sharingan.
Unlike Setsuna, other Uchiha are not good with their mouths. So when this disadvantage proposal was proposed by Tobirama, Uchiha didn't know to refute Tobirama. On the Hashirama side, he also listened to both sides and found that Tobirama was correct.
So every time they met, Uchiha always lost, and they were feeling squeezed out. Because of Tobirama Senju.
Today, Tobirama wanted to compensate. No, actually, he wanted to propose a police force for the Uchiha clan. He believes that by letting them become police, their sharingan won't awaken, and they can also monitor the Uchiha movement.
He believes Hashirama will also agree with this proposal. But unexpectedly, Setsuna joined this meeting.
"Isn't it that you are doing a mission with Shiro?" asked Tobirama with a stern face.
"Ah, don't worry, I use a shadow clone to do the mission," said Setsuna with a smile.
"What, are you disrespecting your mission?" shouted Tobirama.
And then his shadow clone that has done his job was going 'poof', he then noticed the mission went well.
"I just finished my mission," said Setsuna. "I have a question for you, why does Shiro Sensei keep giving me missions? Every time there is a meeting, suddenly
