Non-realizability of the spun Kishino knot

Let $KI$ be the Kishino virtual knot, and let $S_T(KI)$ denote its spun virtual $2$-torus obtained by the construction $S_T(F\times [0,1],K)=(F\times S^1\times [0,1],K\times S^1)$. A virtual knot is realizable if it is represented by a classical knot. Spun Kishino non-realizability conjecture. $S_T(KI)$ is not realizable. The preceding results show that $S_T(KI)$ has the group and quandle of the unknot but a nontrivial biquandle; alternatively, it could represent a nonclassically realizable virtual knotted torus, so its realizability remains unresolved.
