  Recently, the level two analogue of multiple polylogarithm function ${\rm
A}(k_1,\ldots,k_r;z)$ and Arakawa-Kaneko zeta function $\psi(k_1,\ldots,k_r;s)$
were introduced by M. Kaneko and H. Tsumura, for $k_1,\ldots,k_r \in
\mathbb{Z}_{\ge 1}$ . In this paper, we investigate some of their special
relations. In particular, we prove some explicit forms of ${\rm
A}(k_1,\ldots,k_r;z)$ and $\psi(k_1,\ldots,k_r;s)$. Also, we introduce a level
$m$ anlogue of the Arakawa-Kaneko zeta functions.
