Sora is a virtual character within the mobile game "ILive!", serving as Tomoki Takashima's primary romantic interest. She possesses blue hair and exists exclusively as a two-dimensional entity. Takashima affectionately calls her his "waifu," demonstrating intense devotion and openly prioritizing her over real-world relationships. This fixation manifests in collecting Sora-related in-game items and deep emotional investment in her virtual existence.

Sora represents Takashima's explicit rejection of three-dimensional relationships. He consistently expresses disinterest in real girls, attributing his romantic fulfillment entirely to Sora. This dynamic shapes his interactions, as he openly compares real people unfavorably to her and structures his life around the game. His connection deepens when he attends a live "iLive!" performance and encounters the real-life performer embodying Sora. When the original actor becomes unavailable, Takashima temporarily assumes the performer role himself. This illustrates Sora's role in facilitating his personal growth and social engagement, despite her fictional nature.

Narratively, Sora functions as a grounding element for Takashima's "chuunibyou" tendencies, channeling his eccentricities into devotion for her. Her existence remains confined to the game's digital universe, with no physical manifestation or direct interaction outside it. Takashima's relationship with her consistently reinforces his self-identified otaku status and preference for fictional companionship.
