He creates Akatsuki organization but their only purpose is because MC felt like it. It it MC is strong as God and they are weaker following his footsteps.
1. MC wants to return back to earth leaving his dream of being a Ninja for his parents, why because he think they will be sad... Dau of course they will be sad losing their son.... Ok it's being a good son so it seem legit.
2. At the end he need to return home he fights with demon empress for 3 of 3000 weapons he needed to return home.... Yes You heard it right the empress only have 3 of 3000 weapons (every realm has a single weapon and there are 3000 realm) needed for him to go home, so let talk about there battle now, at the near end of his battle what does he do...... Just thinking about it gives me cancer. He uses Sharingan and makes the moon in infinite tsukuyomi hypnotize everyone in all 3000 realm and gets the treasure he need.... f**k
3. He could Cleary have kept the weapons so he could return back as he took few people with him and they might want to return back home but no, he wants the weapons to return.
4. 100, 000 years Demon Empress fights 100, 000 years killing millions people to return back earth where she lived for 20 years.... Now that's f**ked up logic.
