In this world, a person’s past life karma determines their Rank at the time of their rebirth. A man who was so virtuous that even god was surprised was rebirthed as the son of an aristocrat, Alexander, where he started his SSS-Ranked life! With wits as his weapon, he meets any expectations to the dot and establish his position with lightspeed! The curtains to the greatest successful life opens is raised!
Despite being a 'middle aged man' he has no problem being engaged to another child... or a flirty 16 year old girl. Both obviously underage. Honestly, I hate that, but that's not the only reason I rate this so poorly. The art is lazy and most of the panels have the background as a simple gradient or some random lines, if not completely blank. The story is just your everyday OP isekai where the MC is reincarnated and is stronger than anyone in history and automatically seems to be able to use that strength with no issue or dissonance... it's just boring. There's nothing to keep your attention. It holds no value or hints of a plot. However, if you're just looking for a time waster, it is at least isekai content. But that's it.
