Warning wall of text incoming but this should help with cheating on vx and mv games.
This won't let you gen in items unless you have some (usually 3-5) already but using cheat engine on vx is possible I do it all the time. Go

copy the scipt then follow the instructions further down and it should work on just about any vx/vx ace game. I've used it on 20 or so games including this one. and it worked on them all. I have heard reports of it failing.
To speed up grinding use CE's speed hack to get through animations quickly. It usually caps at 5-6x. Locking hp is possible but it won't work if you take enough damage to get 1 shot. Similarly you can use that to get killed easily by setting your hp to 1 or get infinite gold. I'm not very good at explaining things so I'll point you to a tutorial instead of doing it myself.
Just follow

tutorial but change 4 bytes to "rpgmaker vx type" (from the script above) and keep scanning until you have 2-3 results than just try until the changes apply. It should take 4-5 attempts on this game but it varies from game to game. You can get just about any value using this method including xp, lewdness, number of bjs, creampies, ect.
There's also
this for those of you who are okay with less functionality (has quick gold, items that let you insta kill enemies and yourself among other minor things) but don't want to deal with the headache that cheat engine can be at times. There's also something similar for mv (which I could never get cheat engine to work on) here, and is kinda awkward with the controls (takes some getting used to) but it offers agruably more funtionality than cheat engine does. You can find it
here. Don't be an idiot like me and press the wrong f-key reseting you game and losing hour of work.
For those of you who want to die quickly the legit way there is an accessory called a cursed stamp that sets you defense and magic defense to zero in the first town (from ch 1 pre-divergence after your becoming a knight test) it is missable depending on what path you take (at least up to ch 3 resistance path). Just an fyi save often because going willy-nilly can cause crashes.
Also in my experience with oneone1 rpgmaker games (played 5 to varying extend counting this one) save editors don't work. If you have any more questions pm me or quote me here and I'll try my best to answer. I'm not very active though so you may have to wait quite some time for a reply.
