Something that brought the all mighty god to his knees, brought dread into his life and laced days with desperation... paperwork. Over the years Rimuru has been accepting Summon calls more and more often to get out of his office for vacation. 358 years passed after he defeated Yuuki and became a literal god. Yet in recent years people stopped calling him from other worlds. After 10 years of not a single summon request, an idea struck his slime head. Rimuru : "AAAagh why is no-one calling for me. There is a literal god wanting to help you...... Oh... I know..., Why don't I just go to another world my self.

Rimuru was killed and ended up in Danmachi. While he explores the dungeon and the not dungeon (Orario) he will be looking for a way to get back home. Little does he know there might not be a home to return to for a kingdom without its king quickly falls to ruin. (Light novel spoilers.) Also, Rimuru is heavily nerfed... for now. Still in the process of reading sword Oratoria so if I miss a massive plot point that's probably why. periodic updates.

(spoiler warnings for vol 12 of the lightnovel for Tensei slime) Danmachi x TSSDK A country loses its king, and another gains a final boss. Having died in the war with the eastern empire Rimuru finds himself in a completely unknown structure. with nowhere left to go and no particular goal in mind, he wanders upward. The gods of this new world sense something amiss with the dungeon. Some grow intrigued. Others fear the worst. Is the dungeon city Orario ready for the dungeon's final challenge? (I am not fully caught up on sword Oratorio at the moment so if any inconsistencies pop up that's why. also, vol 12 spoilers for that time I got reincarnated as a slime this version of rimuru is the version that chole talked about at the beginning of vol 12 who died in the war because he never evolved to a demonlord. on top of this, I'm going to take some creative liberties and change some events from danmachi to fit my story.)
