I'm trying to see if there are any routes I haven't seen yet. I'm using version 2.67. This might turn into a ham-handed overview guide as well but who knows. That being said I'm not going to talk about the ending for choices along the way, like lying to the two adults in the city since that one choice causes game over. If I miss anything please let me know, I'm looking for significant paths. I also wish there was a way to do multiple paths like mentioned in my city section.
Train: (Only game overs I've seen aside from wrong dialogue choices)
Of course there's the corruption along the way and by not having the police called on the NEET you can have Elulu get more corrupt with rules and such.
Clear miasma fully clothed - Fully clothed gives me an ending at I believe I've done this option at nympho 0, 1, and 2.
Clear miasma nude - The nude option I've only done at nympho 2 and 3 that got me a new background and continuing with that data finally gave me the hair brush option in the menu. I could also edit some value in the table such as miasma, MP, HP, etc. after this route.
Office Street:
BJs - Once touched enough by the two businessmen men look up what they're doing yourself at home. I selected the medical degree (diagnosis, IDK it was a while a go and I can't find the save for the exact phrasing), and forced Elulu to cum evey time.
With this route Elulu gives HJs and BJs and deep throat. Cum will be on face and swallowed in mouth. Doesn't progress further.
Exhibition - Once touched enough by the businessmen don't look up what they're doing at home. I also selected persuade to cum every time instead of force to cum and to focus on purification instead of trying to resist cuming. Ultimately the police officer can strip Elulu of her shorts (panties) or skirt BUT NOT BOTH (I have to have the cop strip the skirt and the NEET to take panties and that combo worked but not much came from it). I also discovered the options in Elulu's closet for her to have her blouse open and panties either down or hanging on to one leg. Also the ability to remove her headband through the option menu. TBH I don't know if the headband option was unlocked prior to this route but I do know that I cannot remove it through the closet. Elulu basically gets eaten out and played with on this route by the citizens. Don't progress to her getting nude and walking around though I think I might try that option later if Elulu can leave the train while nude. Edit: It seems Elulu cannot leave the train if she's missing blouse or skirt at least where I'm trying.
Out of Town:
Get kidnapped by the group of guys and have the various options there. I don't know how to get Elulu released from captivity so I take it this is unfinished/deadend.
Anyways, there's what I know, hopefully we can add to this to make it complete or I can answer questions. I don't have save files for these routes or their junction points though, sorry just thought of making this post this morning.
