Sword Art Online: Fatal Bullet has Pillow Talk events, like other games in the series, where raising affinity with characters will allow the player to engage in an intimate conversation while sleeping on a bed together. However, Kirito isn’t the only main character around. [Thanks, Ryokutya2089]
Playing through ‘Main Story Mode’ and ‘Kirito Mode’ will let you engage in Pillow Talk events with different characters. The list of characters available in each mode were recently revealed:
Main Story Mode: Kureha, Zeliska, Strea, Philia, Rain, Premiere, Itsuki
Kirito Mode: Asuna, Leafa, Sinon, Lisbeth, Silica, Yuuki, Argo
It seems that Kirito’s choices are based on the characters who originate from the novel series, while the avatar character can choose to have Pillow Talks with game-verse characters. Itsuki is also the only male character available, and can engage in Pillow Talk with the main character.
Sword Art Online: Fatal Bullet releases in Japan on February 8, 2018 for PlayStation 4 and Xbox One. A PC version releases alongside the Western release on February 24, 2018.
