I'm in the first half of chapter 9 and finally unlocked these. I'm not sure if it's worth creating and training one or the other of either or both of these at this point in the game. Are they worth the time and effort?

Sorry for crappy screen shoots https://i.ibb.co/3skbLTj/Petta1.png So i recruit Petta in Petta mode by wishing to fight badass daughter in the game. It have different cut scene compared to fighting her in main story line, but turns out you won't get 02 and 03 from image viewer if you recruit her in Petta mode. Which sucks....i mean wtf, i also been looking internet but there is no image viewer of 02 and 03, so maybe someone can show me the link image of 02 and 03 ? it was the strongest daughter for 02...

I'm trying to find something that might cause that. I don't get why sometimes it boots up just fine and other times it just pulls up a blank screen and hangs. Not sure what to do about that

... For a NIS game, anyway. Only 1 map for a base? Only 4 facilities allowed out? There are no INT buff facilities? All the units unlocked by the 5th netherworld? No offense, but other NIS games around the same era (Phantom Brave, Disgaea, etc.,) looks as if they got more love than this one got. Jus sayin....

So i want to max my Yoshitsuna, the cost were crazy. At lvl 2000 it already cost 2 million MT. So i heard Professor and Laboratory will decrease the cost when we modify leveling it. So do the Professor need to lvl higher right ? if my Yoshitsuna lvl 2000 and my Professor were lvl 2500, then the cost will much cheaper. Also do the Professor and Laboratory level can be combined and affect the cost like if my Professor and Laboratory were lvl 2500, then it become 5000 level total, So the cost of Yoshitsun...
