Notes:
Structure of the story: This story is made up in a structure that has two parts. One is the normal chapter format. The second is a flashback. How will you know the difference?
Chapter = normal text, lengthy.
Flashback = italicized text, usually short. They are very important!
This whole story is written in the third person omniscient, but from Yuuri's perspective only. So, Conrad and Wolfram's thoughts are only revealed when they talk; all other times they are only Yuuri's assumptions on their thoughts.
Warning: I haven't seen the third season, so this ignores any information that may have come from it.
Eight years have passed since Shibuya Yuuri's first arrival at Shin Makoku, and in that time, relatively little has changed about the young king. He is-of course-not quite so young anymore, his Earthian link allowing him to sprout up to full height well before his 90th birthday; his youthful, round features have given way for the sharper image of a man in his prime. His hair falls a little closer to his shoulder, though not as long as the Maou persona of his youth. That persona is long gone now, having made a successful merge with the person it always was-just another facet of the young king-and Yuuri wields that same power as before, just with more efficiency.
Shibuya Yuuri still loves baseball, although not in the obsessive way he once adored it as a child. He's still not particularly eloquent in comparison to other leaders, but he does his best and has even willingly learned the customs and history necessary to be a fruitful leader. He is still an idealist in the sense that he wishes for peace and works hard to achieve it everyday, but he is also aware that there are people who will never be swayed, people who just want hardships to exist even if they may not be evil themselves. He has learned to fight for this ideal of his, but now knows fighting blindly is fighting foolishly.
Little has changed about Shibuya Yuuri other than the effects of Time and the lessons It has taught him. Yuuri has grown up, and he has learned how to compromise. He has also learned the different ways in which a person can compromise; what he himself has come to compromise and why.
This is a story about choices.
