Ok, I have to say that. Maybe I'm not even first. Did you knew that "Maika" sounds like russian word for describing t-shirt? And "Reika" sounds like russian word for describing wooden lath. Sounds funny for me. Anyway, design is great.
That's pretty interesting. As the characters and story is set in Japan, their names take after Japanese meanings, though that's interesting to know that they sound like words in another language with totally different meanings.
