Psychologist Su Yu found himself becoming a "ghost" in the Naruto world.

An immortal, yet indestructible, Impure World Reincarnation that cannot fight, cannot be perceived, and even has no sense of taste.

His only obsession is to truly come back alive.

"Ding, strong emotional distortion detected, rescue mission initiated."

【Mission 1: Uchiha's Twilight】

Clue 1: Appease your best friend Uchiha Kagami and obtain the "Mangekyo of Trust".

Clue 2: Stop Danzo's "root of genocide" plan.

Clue 3: Give young Fugaku a psychology lesson called "Love and Peace."

Mission 2: The Three Ninjas' Crossroads

Challenge: Enlighten Orochimaru, who is obsessed with immortality, and make him understand the meaning of "living".

Challenge: Cure Tsunade's hemophobia caused by the death of her lover and brother.

Challenge: Tell the confused Jiraiya that there is more than one choice for the "Child of Prophecy".

In order to get the reward of real taste, Su Yu began his journey of redemption through "mouth persuasion".

He saved Kushina, but made Minato wary of him; he stopped Obito from turning evil, but made Rin develop feelings for him that went beyond friendship; he changed the tragedies of countless people, but found that Nagato's Reincarnation Technique might never be activated.

He healed the entire ninja world, but was getting further and further away from his goal of "resurrection".

When Black Zetsu regards him as his greatest enemy, and when the whole world is searching for the true identity of this "Eternal Sage".

Su Yu sat on the Hokage Rock, looking at the ramen exchange voucher in his hand with distress.

"I saved everyone, who will save me?"

Thanks for the invitation. I'm in Teyvat, working part-time...

Until that day, when the task lottery system was awakened... as long as you complete the task, you can enter the lottery.

So, in order to complete the mission...

Eula: You're telling me now that your confession is fake... I absolutely don't agree. You must be afraid of being rejected. Don't worry, my love, I will tell you my love...

Shen He: You are the red rope that can tie me up, so those who come to disturb us have to disappear.

Kamisato Ayaka: Complete the mission? Is that your reason? Well, I'll give you a mission too.

Yi Chen: Hehehe, I must survive!

On the app called FreeFriends, he met Saki Kawasaki, a woman short of money due to a family change. On the train, he encountered Kotonoha Katsura, a cowardly girl who was bullied at school. He became a model and met Kirino Kousaka, a girl who loved the anime. From that month on, Yuu Kasugano's youth was no longer normal.
