Suguha: Don't call me Leafa!

Suguha first thought virtual reality was a bad thing because it took her brother away. When she first go into ALFheim Online, she is captured by the beauty of the world as she soars high in the sky. She finally realizes why her brother (cousin) loves the virtual world. At Suguha's school, Nagata pops out of the corner, and when he calls Suguha, Leafa, Suguha yells at him not to call her by that. Suguha mentions she has to show the way for a player, and Nagata wonders why she is traveling with a shady guy. Suguha pokes Nagata for implying something else. Back at Suguha's home, she puts on her shirt over her undergarments and logs into the ALFheim game. At the cafe, she meets up with Kirito and leads him to a giant tower. Inside, Sigurd asks her if she would leave the party, and he says if she left, it would damage their reputation. Kirito comments that party members are not items, and Sigurd finds Kirito a threat due Kirito being a Spriggan. One of the men tells Sigurd not to attack Kirito in town because of their reputation. On the top of the tower, the two gaze upon the sky. Yui pops out and says that she doesn't understand humans at all. She tells them to be direct as she smooches Kirito's cheek. Suguha (Leafa) finds Yui an impressive Private Pixie. Retcon arrives to the scene and informs Leafa that his sword belongs to her. He tells Kirito to watch her, and before Retcon can complete his sentence, Leafa steps on his foot to shut him up. In the skies, Yui asks Leafa if she likes Retcon since Retcon likes Leafa. Leafa quickly denounces it.
