before Suguha had realized it, their relationship had fallen to a merely normal one. But truth be told, Suguha constantly felt lonely. She wanted to talk to her brother more. She wanted to understand her brother’s world, wanted her brother to come and watch her competitions. However, just when she was about to express these feelings, that incident happened. The nightmarish incident named “SWORD ART ONLINE”. Ten thousand youths from across Japan were confined by an electronic cage and fell into a long sleep. Her brother had been admitted to a major hospital in Saitama. Then, on the first time Suguha had gone to visit him... As she saw her comatose brother, restrained to the sickbed with numerous cords and concealed by that dreadful headgear, Suguha burst into tears. It was the first time since her birth that she cried. She simply clung to her brother and wept aloud. There may never be another chance to exchange words with him. Why didn’t she try to close the distance between them earlier? It shouldn’t have been that difficult; it should have been possible for her. It was then that she began to seriously reconsider whether she should continue to practice kendo and what her true feelings were. But she was so lost that she never found an answer. During her fourteenth and fifteenth years when she couldn’t see her brother, Suguha had entered a high school based on recommendations from others around her, but whether she should continue walking down this path was a doubt in her heart that would not disappear.
