From Terra to Terra, the Star Emperor's Vacation

(Currently, the outline covers the following worlds: Arknights, Super God Academy, The Three-Body Problem, The Wandering Earth, Warhammer 40k...)
"What, a trip paid for with public funds? I've served the empire diligently for 500 years, what's wrong with enjoying myself a bit?"
"Beast-eared girls? I'm a kind-hearted person and can't bear to see beast-eared girls leave their homes, so I took over their planet as well."
"An angel...it would be even better if her personality wasn't so awkward..."
