Assembling Visual Novel Sprites

[aizsenpai]

Hello, I'm currently ripping sprites from Nekopara Volume 3 for some misc work to convert into Live2D, and was wondering if there was an easier way to split and reassemble these sprites into a PSD.

Edit: Attached example

Going through Garbro had me find various .pzs files, which I then decompiled into PSB's which allowed me to find the various sprite sheets, and .json files
