『才能』って嫌いな言葉だな～。それって、そんなに大事？ それがないと生きていくこともできない、内臓か何かなの？

Author's Comment
"I was in charge of the scenario for Rocket Start. Marionette was written from the viewpoint of Nazuna-san, and Element from the viewpoint of Eichi-san, but this time around there is central point of the sort. We await the entrance of Transfer Student-chan." [1]
