These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ho Yay: Mirai and Ryu, to the point they are Mistaken for Gay in episode 24. After Mirai and Ryuu possessed by Yapool have a stare off, George asks "Don't tell me you two are like that!" When Ryuu possessed by Yapool replies, "Actually, we have a secret we can't tell anyone," George and the others go into shocked hysterics.
