There's something admirable about Riku is very earnest in his method despite his questionable actions that I can understand why people flock to his charisma more, so I enjoy him actively working hard for his goal. Watching the close bond between Reimi and Riku is also nice since before, they didn't have a moment to simply have heart to heart. Also, despite being a despicable person before, Hain has become too much of decent person in a quick period of time that it's a major whiplash.
