Shin Uchiha understood Tsunade's concerns.
The Second Hokage, Tobirama Senju, had always been particularly hostile toward the Uchiha Clan.
Just looking at the ninjutsu he had invented made it clear that many of them specifically targeted the Uchiha Clan's Sharingan.
For example, the Multiple Shadow Clone Technique was a clone technique that even the Sharingan could not see through.
The Flying Thunder God Technique had originated from the Flying Thunder God Slash.
That was right-the very ninjutsu that had killed Madara Uchiha's younger brother, Uchiha Izuna.
Then there was the genjutsu he had left behind, the Bringer-of-Darkness Technique, which could strip all light from its target's vision.
Who do you think that genjutsu was meant to counter?
As the most famous dōjutsu clan in the shinobi world, the Uchiha Clan probably had something to say about that.
So, yesterday, when Shin had discussed reviving Senju Nawaki with Tsunade, he had also wanted to use Impure World Reincarnation to summon Hashirama Senju and Tobirama Senju from the Pure Land, giving her a chance to reunite with them.
Knowing all too well how hostile her Second Grandfather had been toward the Uchiha Clan, Tsunade had grown worried about their meeting.
Once Shin Uchiha understood what troubled her, he found it a little amusing. He gently pinched her soft cheek and said:
"If you're that worried, why not hold off on summoning your Grandfather and Second Grandfather? We can talk about it later."
Hearing Shin's words, Tsunade breathed a sigh of relief. She really did not have the courage to face her rather stern Second Grandfather right now.
It was not that she feared him. She feared hurting him. After all, his most beloved granddaughter had ended up choosing the clan leader of the Uchiha Clan, whom he had opposed his entire life,
