Caleb Character Guide: Profile, Personality, and Best Memory Cards

Caleb is 25 years old, 188 cm (6'2") tall, with dark brown hair. His birthday sits under Gemini in mid-June: the game's native Chinese profile and the English wiki both list June 13, while a separate English aggregator lists June 12 — a one-day gap between sources that hasn't been reconciled, so this guide follows the native/wiki date.

He is a former DAA fighter pilot who now serves as a colonel and executive officer with the Farspace Fleet, and carries the Gravity Manipulation Evol — the game's native source names this element specifically, while some English aggregator sites describe it only in the vaguer general terms of "energy manipulation."

Caleb is the newest of the five Love Interests, added January 22, 2025. He is a childhood friend of Zayne, and the wiki flags his early relationship arc with the player as carrying a sibling-like dynamic before it develops romantically. He is close to his adoptive grandmother Josephine and best friend Gideon, and has an established rival in a character named Viper.

Caleb has three 5★ Solar pairs (two are confirmed Myth):

• Farspace Bloomfall / Farspace Deprivation — Ruby stellactrum, DEF-focused, released alongside his debut.
• Loneroad Together / Loneroad Unreturned — Violet stellactrum, ATK-focused.
• Nether Yearning / Nether Parting — Emerald stellactrum, HP-focused.

Community meta notes call Caleb the most versatile of the five Love Interests in combat, without one standout Myth pair dominating tier lists the way some other Love Interests' pairs do. Guides generally suggest building out whichever pair color you already own first, matching Protocore Alpha/Beta pieces to that exact Stellactrum color, rather than chasing one specific pair as a must-have.
