Mugen Houyou:Walkthrough

Endings aren't actually that hard to get in this game as it kind of pushes you towards them. Previously acquired endings are removed and the same goes for cleared characters.

It does seem possible to clear a character without getting all her H-scenes in some cases. This happened with Keiko and Sera for me, specifically the blindfold and Michel scenes respectively.

If the character is cleared, an option for going to their room pops up above save (right click to refresh if you have too many cleared characters). You can then view all their scenes there instead of the Alice's mansion scene viewer.

There are various types of endings:
 * Game endings require you to play the game normally and picking options from there
 * Personal Pronoun endings/routes are chosen when you pick a pronoun
 * Class change routes/endings are chosen at the name selection screen

The last two types get unlocked as you clear various endings, so don't worry too much if they don't appear.

Game endings
Note that I only saw the generic use end when failing to get a new Hozumi route when she was uncleared, might want to do that one when doing Hozumi routes.

Hozumi

 * Hozumi Suicide
 * Do all H-events, ignore her, punish her and let her fall.
 * Killed by Hozumi
 * An intermediate end. Don't be entirely good or bad and you should get it.
 * Hozumi and child
 * Be nice to Hozumi. Don't H her and give caring responses.
 * Hozumi Love
 * After the other Hozumi endings, the love Hozumi option should appear. Pick that and then pick her.
 * Confined by Hozumi
 * After those endings "do something weird" should appear. After the scene pick refuse.
 * Hozumi's accidental blackmail
 * Same as above, but pick accept.

Sera

 * Double suicide with Sera
 * Check on Sera and let her do as she wishes with Yuki.
 * I sent Michel away, but there is a scene with him and Sera.

Katsura

 * Katsura's happy end
 * Pick work:? for her to get introduced and don't do her. Keep not doing her throughout this route.
 * This should unlock work option to help her. Do these and call for her.
 * Katsura escapes
 * Pick work:? for her to get introduced and do her whenever you can.
 * Don't do her work events either.

Keiko

 * Treatment with Keiko
 * Her events happen after you suffer an attack from your illness, keep working for it to happen.
 * Pick the H options everytime. After a certain amount of time this ending will play.
 * Keiko escapes
 * This will happen if you just ignore her. Keep getting sick (6 times?) you will get an event where you can pick "depends" for this ending.
 * I assume if you pick the other option, you'll get the blindfold scene.
 * Keiko's fetish treatment
 * After doing her ends you should unlock "get treated by Keiko", pick that and go through with the treatment.

Yuki

 * Yuki old age
 * Pick Yuki events and the singular call Sei. H her and stop Sera. Only get S&M'd by Ayaka (nothing else) and then go steal her back for this end.
 * Sleep with Yuki
 * Do Yuki events and the singular call Sei. H her and stop Sera. Reject Ayaka and leave her be. As the final option you should pick "Don't want to die".
 * Yuki with child
 * The same as above, but give up instead.

Sei

 * Sei end
 * Keep working and never rest.
 * Might need Keiko to be completed so she doesn't interfere.
 * Sei goes to the moon
 * Do the car jobs and buy the rocket, this unlocks the rocket option in the job screen. Pick that and then pick Sei.
 * Love with Sei
 * The option "foster your love with Sei" should be available after his other ends. Keep picking that and then "cross the line"

Ayaka

 * Killed by Ayaka's negligence
 * Similar to the Yuki route. Just refuse her scenes, but still steal her back.
 * Ayaka and treatment
 * Accept all her scenes in this route. Stop Sera, doing Yuki seems to not be an issue. Steal her back

Sayo

 * 3 of them to Switzerland
 * Do the department store jobs till you get offered Sayo and take her in, send her to live with Sera. Keep checking on them and then pick to become a family.
 * Life with Sayo
 * Do the department store jobs till you get offered Sayo and take her in, take care of her yourself. Keep doing her events and finally pick adopt.

Other ends

 * World conquest
 * Do all the military work and get the missiles and then do real estate. This seems to unlock this option.
 * Pick the World Conquest jobs and then "bring down the missile".
 * World conquest failure
 * The same as above, but pick "defeat Russia" instead.
 * Island's living god
 * Do the real estate jobs until you can move to the island, do so for this end.
 * Black Box
 * Do the military jobs until you get the black box, then immediately press it.
 * Killed by Opium
 * I had to sleep twice when I could and then call for Opium.
 * No one is here 1
 * After some clears you should have the option to pick up a ball, do so and pick "remember" after some events.
 * No one is here 2
 * After some clears you should have the option to pick up a ball, do so and pick "don't remember" after some events.
 * General purpose
 * I only ever got this when messing up a Hozumi end. For example, get her killed by end and then try to do that end again.

Personal pronoun endings

 * Pick オラ, you will now play the Tagosaku route which has multiple endings
 * Go into the left room and find Ayaka
 * Go into the right room to find Yuki and try to do her.
 * Go into the right room to find Yuki and don't do her.
 * Pick オラ２ for the Shin-chan end
 * Pick オラ３ for the Goku 1 end
 * Pick オラ４ for the Goku 2 end

Class change endings

 * Pick 老人 for the elderly end
 * Pick 神父 to play as Arima, this has multiple endings
 * You fail if you are out of rings during the boss fight, just visit all the rooms and fight the youkai.
 * You succeed if you keep one ring to fight. Pick a room and fight a youkai, look around in the hall and go to the courtyard to pick a flower, then beat the final opponent.
 * Pick ちんちん for the penis end
 * Pick 師匠 for the master end
 * Pick Sayo (or whatever you named her) for the become a child end
