Dorei Tensei: Sono Dorei, Saikyou no Moto Ouji ni Tsuki

If you consider reading this story, ask yourself this: am I okay with the previously legendary powerful prince as protagonist being intermittently enslaved, insulted, treated as less than human, his achievements obtained by his “master”, happily ignoring his own initial goals and dutifully embracing leash on his neck? If you can bear with this, you are in for a treat – this story is pretty great, with plethora of (sometimes predictable, but still nice) twists, despite pandering to the Master-Slave fetish. The characters are mostly cardboard cutouts with flat backstory and zero development, besides some shallow power-ups; still, they are entertaining and ridiculously cutely drawn. That’s the major upside – while the author failed to write engaging character-driven plot, he delivered amazing artstyle, breathtaking action scenes, and powerful peak moments.

If you don’t really care about extensive worldbuilding, character development and can ignore your pride’s responce every time MC just goes along with slavery (instead of, y’know, look for ways out to more conveniently follow his goals) – this will be a fun, if sometimes slow, 7.5/10 experience.
