Being Low as Dirt, Taking What's Important From Me

"Protect that girl from an untimely death."

That is the mission given to me and my senpai by the heavenly realm. What kind of a job is it...... to come to Earth to protect some stupid human? She's just an ordinary girl......? Why do we, heavenly angels, have to do such a thing! Senpai must have been thinking that way, too, or so I thought—?
