I ended up in the world of Naruto, and now the System wants me to go back?
There’s no way I’m going back in this lifetime. The people here are good-looking and pleasant to talk to, so why would I leave?
“Tsunade, I’ve got a Zanpakuto called Minazuki. It has incredible healing powers, and its Bankai comes with a surprise!”
“Naruto, want to see your parents? I can bring them here right now.”
“Sasuke... go get beaten up first, then come back.”
“Kushina! This thing will let you settle the score with the Third Hokage, and it can even destroy the shinobi world!”
Minato: “Please don’t!”
Not bad, more quickly! Devil's High School, Fairy Tail, the Outlaw Princess, and everything that comes from the sky are also included.
