The hardest thing about getting invested in Riku's trial for this arc is how little he showed any hesitation, doubt, or struggle when it comes to interacting with people, unlike when he was battling with powerful people - to whom he often loses outside the first episode. It makes him a bit pathetic as a protagonist, and there's a lack of show of how the villagers benefited with the rise of Chikyu outside of being more capable than the average person. It's glorifying the use of reiki as a tool to boost people without any cultural significant behind them, so it lacks substance.
