When Natsume Enters a Battle Anime

Recently, Xia Mu received an order from the authorities: the Time-Space Army was exploiting cracks in the space-time continuum to disrupt the future course of various eras. He was ordered to set out immediately and eliminate them to preserve the order of time and space.

Time and Space One:

[Mission Location: Namimori Town, Ten Years Later]

[Mission Objective: Prevent the Tenth Boss of the Vongola from being killed]

Time and Space Two:

[Mission Location: Konohagakure]

[Mission Objective: Stop the Nine-Tails from being provoked into accidentally killing villagers]

Time and Space Three:

[Mission Location: Tokyo]

[Mission Objective: Repair the Sword of Damocles]

Time and Space Four:

[Mission Location: Honshu]

[Mission Objective: Prevent the birth of a new Demon King]

The missions weren't difficult. He just had to stay true to himself and avoid interfering too much in his friends' affairs. But Xia Mu never expected that turning down their requests would be just as hard.

Tsuna: "Xia Mu, would you be my outside advisor?"

Naruto: "Haha, here's the appointment letter naming Xia Mu captain of the Anbu!"

Suo: "Mm. They mean to nominate you as the new Red King."

Tanjiro: "Please, take me as your disciple, Master!"

Note: The setting carries over from Natsume the Saniwa and Natsume's Youkai Harem.
