In Cyberse World, Ai used to relax on "Linkuriboh", one of the Cyberse monsters that the Ignis had created.
When Ai returned to the Cyberse World, he found the entire place in ruins, and saw that Linkuriboh was the only being left. "Linkuriboh" was glad to see Ai, and glomped it in happiness. Three months later, Ai returned to Playmaker in LINK VRAINS, and gave Playmaker "Linkuriboh". Ai praised "Linkuriboh" after it protected Playmaker by reducing the ATK of Bohman's "Flow Hydradrive" to zero. Ai returned to Yusaku's house, and was glad to see Roboppy again. Roboppy, however, was infuriated about "Linkuriboh", Ai's additional minion, and saw it as its rival, while Ai thought of itself as popular.
