Risa Shiramine, best friend to Kaede Honjou, introduced her to NewWorld Online under the alias Sally. Restrictions from her mother initially prevented Risa from playing alongside Kaede, requiring her to pass a real-world test first for game access.

In reality, Risa sports ash brown hair and eyes, typically dressed in casual sleepwear with her hair loose. Her in-game avatar mirrors this closely, featuring ash brown hair held up by a white ribbon and framing bangs. She began in a starter outfit similar to Kaede's, later upgrading to specialized mobility armor: a gray turtleneck beneath a silver breastplate, a gray coat with blue accents, puffy shoulder pads, a blue scarf, extremely short jeans, a white belt with a golden buckle, dark grey knee-high boots, and blue-and-black striped socks. She wields two ornate daggers with gold-accented handles. Within her guild, she stands as one of the shortest members, merely one inch taller than Kaede.

Extroverted, cautious, and practical, Risa leverages extensive gaming experience. Her creativity fuels unconventional strategies, leading her to choose the swashbuckler class to complement Kaede's defense rather than a traditional support role like a mage. She enjoys sports and swimming, traits translating into high real-world reflexes mirrored in-game. Confident in PvP, she harbors a pronounced fear of ghosts and horror elements. During competitive events, she displays aggressive determination, exemplified by her extensive player eliminations in the second event to secure silver medals.

A professional gamer with multiple championship awards, Risa selected twin blades after discussing class synergy with Kaede. She possesses exceptional evasion capabilities, honed through repeated failures in other games, which significantly improve under concentration. She continually refines her techniques, adapting evasion tactics after observing a player named Dread to focus on instinct and fear-based movements.

Risa co-founded the Maple Tree guild with Kaede, later delegating the guild master role to her. She actively strategizes to ensure the guild's success and maintain parity with Kaede's unconventional playstyle. Key developmental moments include orchestrating the "red moon massacre" during the second event, dueling Frederica to validate skills like Attack Guidance and Running Water, and refining her combat approach post-encounter with Dread.

Her relationship with Kaede remains central, driven by a desire to see her succeed within the game. Risa maintains a supportive yet challenging dynamic, leveraging her veteran expertise to bolster their collective efforts.
