I would like to call it the creation of fandom! Only those who haven't seen it, who don't want to finish it in one sitting after watching it, [poor] The characters of the two Bats and Sens are captured so accurately. The world view setting of catastrophic fusion is also very catchy. The process of facing crises again and again and resolving them is simply not too fascinating. The sadomasochistic love between the two young lovers in the later period is also very heart-wrenching, but love cannot be stopped by anything, and everyone has a tomorrow.
