In this study, we investigate the line emissions from cold molecular gas based on our previous ``radiation-driven fountain model'' (Wada 2016), which reliably explains the spectral energy distribution of the nearest  type 2 Seyfert galaxy, the Circinus galaxy. Using a snapshot of the best-fit radiation-hydrodynamic model for
the central $r ¥le 16$ pc, in which non-equilibrium X-ray-dominated region chemistry is solved, we conduct post-processed non-local thermodynamic equilibrium radiation transfer simulations for the CO lines.
