My Combined Master's and Doctoral Degree

Dazai Osamu thought he was about to die, but in the blink of an eye he became Chaldea's Master and set off with the Fujimaru siblings to save humanity.

At first, he found it pretty interesting. Then life, in the form of every Servant he summoned reaching maximum bond, wore away half his sharp edges.

At last, humanity was pulled back from the brink of death. He thought he could retire and do what he wanted, but in the blink of an eye, he was in Terra.

Dazai: ...Damn.

Starting over from a save point, Dazai grimly studies Catastrophes, Originium, and all kinds of related knowledge. Then he gets dragged into Babel and becomes Babel's demon, even spending several years sealed in a coffin.

By the time he's let out of the coffin, he's become sickly and frail. But he still has to keep working, day and night. Every so often, a donkey rushes in and says, "Doctor, you haven't finished your work yet. You can't rest now."

Dazai: Thanks a freaking lot :)
