This is a great story, the novel was very good as well and the manga is doing a fantastic job so far, people keep shitting on it saying gender bend but in reality they are just mad that the MC isn't broken shitting on everyone like all the other kr and cn stories they love.
I am very glad someone picked this up and are continuing the translation, it's a breath of fresh air that brings hardships, comrades that are actually important and an MC struggling to grow stronger even with all the knowledge and experience he has in a foreign world he knows not much about, especially interested in the angle of being a spiritualist and sword master, think there's a lot of possibilities fusing his power with Naiad(using a water sword instead of an iron sword and incorporating long ranged attacks into his arsenal), and none of this is even counting on the Titans, who have yet to be a major part in the story, especially excited for when he starts using his titan, which for all intents and purposes is a pretty broken titan in this world.
