Who doesn't like reading about debts.... Normally the debt collectors in manga tend to be the bad guys, but here it's all about a good guy who collects old debts: The protagonist of "Gikou Taiyo no Torikaeshi: Toichi tte Saisho ni Itta yo na?" can actually lend skills, but only for a price! So when his group wants to throw him to the monsters, he decides to collect their accumulated debts and soak up their massive credit mountain. Honestly, the idea works surprisingly well - it's also the only thing that halfway works in the manga. It's always about fair payments, yields, debts andhow to calculate them and much more. And every time the manga talks about it, my interest was definitely piqued. What is fair, how are debts calculated or even just our protagonist collecting debts by beating someone up - the unique twist made the manga worth reading again and again.

Unfortunately, the rest of the manga is nothing more than a very generic, mediocre slop, which I wouldn't recommend precisely because it opens up all the generic themes from revenge to nation-building in 37 chapters, but doesn't go anywhere and so couldn't convince me.
