Yet another mix of fantasy and adventure. Now, novels like these aren't what I normally read. Mainly due to the whole reincarnated, angelic to human vibes. What keeps things intriguing is the MC's (Kaijin's) desire to protect the world.The world-building is solid. Dude checked off the fantasy boxes: celestial beings and magical powers. In terms of the plot, it's not bad. Kaijin seems complex but promising as the story progresses. The other characters are also a tad interesting, specifically the MC's mentor.If there's any advice I'd like to give, it's to speed up the narrative. Feels a bit slow at times. I'm sure that's because it's still a new story and that the action-packed scenes and character developments need to be expanded first.
