As one of a series of papers reporting on a large reverberation mapping campaign, we apply the maximum entropy method (MEM) to nine narrow-line Seyfert 1 galaxies with super-Eddington accretion rates observed during 2012–2013 for the velocity-delay maps of their Hβ and Hγ emission lines. The maps of six objects are reliably reconstructed using MEM. The maps of Hβ and Hγ emission lines of Mrk 335 indicate that the gas of its broad-line region (BLR) is infalling. For Mrk 142, its Hβ and Hγ lines show signatures of outflow. The Hβ and Hγ maps of Mrk 1044 demonstrate complex kinematics—a virialized motion accompanied by an outflow signature, and the Hβ map of IRAS F12397+3333 is consistent with a disk or a spherical shell. The Hβ maps of Mrk 486 and MCG +06-26-012 suggest the presence of inflow and outflow, respectively. These super-Eddington accretors show diverse geometry and kinematics. Brief discussions of their BLRs are provided for each individual object.
