Genuinely changed my life, any of this mangaka’s work are amazing but this one just…the characters dynamic, the struggles of the main character and the way the love interest showing him genuine kindness helps him stand up again…amazing no notes

The art is GORGEOUS, and every character is unique and interesting. The biggest draw for me is the lore, be that character backstories or world building. Great comic

A dynamic I love and an incredible take on the effects religion has on power gaps between the rich and poor (and MORE, because religion can effect a bunch if you but your mind to it in creative ways)? In beautiful black and white?? It’s on going but I can’t wait to see where the story goes.
Houseki no Kuni. It's so beautiful, and it has some extremely dark elements that add so much depth. The character development is quite interesting as well, especially with the main character. It's got a lot of those love-hate-love-hate character relationships with the reader as well. I have to say, it's somewhat formed the person I am today tbh.

Tell me your favorite manga/manwha/manhua on this site (or not on this site idc) and tell me why it’s your favorite. No judgement, just pure optimism.
