Episode 12 is starting to get more complicated. This episode shows more about the relationship between the mother and Tsukasa, as well as her possible intentions. However, the floating girl is still not explained, and I still do not understand what her purpose is. This episode also makes me wonder why the mother exists inside the game world and why she seems to have the power to control parts of it. Did she create the game, or is there something even bigger behind her? I hope the next episodes will reveal more of these mysteries.
