Alright after messing around with the game for a bit i havent exactly devised a walkthrough, but i can give some pointers.
schedule:
from 10:00 to 24:00. Every action costs time, and after the schedule is complete another 5 minutes is removed, so you want to fill out the schedule rather than putting in 1 command at a time. Universal and limited skills are acquired through finishing anime and idol events. These carry over between games so you might want to just spend the first playthrough doing nothing but watching anime and not bother with sex at all.
skills:
anohana - super peace busters (double love increase rate, universal)
SOA - dual wielding (makes the moe/fujo and love/desire increase be equal, to whatever the bigger number was. So if you get 5 love 10 desire normally, it will become 10 love 10 desire instead)
utapri - quartet night (makes the last 4 options in the schedule generate double stats, universal)
free! - highspeed (makes something last only 5 minutes)
evangelion - AT field (removes motivation loss)
madomagi - time rewind (gives you one extra day, universal)
oreimo - wicked eye (double fujo rate, universal)
yowapeda - koi no hime hime petakko (double moe increase, universal)
k-on - the other side of oblivion (resets watching an anime)
MIX (no idea how i got this one, i think from idol stuff) target action doesnt remove foreplay (meaning sex or any non foreplay activity wont reduce the foreplay counter. Thus allowing you to have her still wet and ready)
stats:
stamina: basic stuff, most training costs stamina, anime and resting generates stamina
motiv: some anime generates motivation, other anime drains it, idol training costs motivation. Also cosplay sex costs a lot of motivation. I have no idea when anime costs motivation, ive had anime that costs motivation in one playthrough generate it in another playthrough
love: from sex, opens up more sex
desire: from sex, opens up more sex
otaku: from watching anime
moe: from watching anime
fujo: from watching anime
idol: from idol training
training:
sex: generates love and desire. Left options are foreplay, these cost little time, little stamina and increase the successrate of the sex options on the right side. Once desire is high enough they level up. Giving more stats on doing them. Sex costs a lot of energy and requires foreplay to have a good chance of success, but generate a lot of love/desire. Viberator and blowjob are special. they cost a lot of energy but do also give foreplay, but you cannot increase their chances. Anal caress is special in that it gains a bigger chance of success with foreplay while counting as foreplay itself.
Results:
foreplay:
kiss love 2 desire 1 (level 1 and 2) (3 love 1 desire for level 3)
touch breasts 2 love 2 desire (every level it seems)
touch pussy 1 love 2 desire (2 love 4 desire at level 3)
touch ass 2 love 2 desire (3 love 3 desire level 2)
sex:
missionary 6 love 6 desire; great result 9/9 (12/6 early on? 18/9 for great early on? Seems that at the start she gets extra stats from missionary.)
doggy 5/8 (8/8 sometimes); great 7/12
cowgirl 8/7; great success 24/10
blowjob 6/6
vibrator 5 desire (level 1) 6 (level 2) 8 (level 3)
anal 10/10; great success 15/15
I have no idea how stats they give you fluctuate, seems that she goes from preferring missionary to doggy to cowgirl.
anime: these give a bonus skill and cosplay if maxed out. However some of them didnt seem to unlock every time in the cosplay tab. I think this has to do with having the right stats/unlocks beforehand. The male h.core means how much otaku points it gives, the male symbol (mars symbol) tells you how much moe it gives, the female symbol (venus symbol) tells you how much fujo it gives.
idol: mostly gives idol points. You have to get motivation though.
cosplay: these unlock from completing anime. They cost massive amounts of stamina and motivation. But give a big stat boost.
madoka costume: 20 love 8 desire 28 otaku 12 moe
soa costume: 16 love 4 desire 24 otaku 6 moe 4 fujo
eva costume: 6 love 18 desire 28 otaku 4 moe 4 fujo
oreimo costume: 12 love 12 desire 19 otaku 16 moe
free!: love 10 desire 14 otaku 4
Tips:
-foreplay seems best to get the most difficult option available, they cost more energy but generate more foreplay points and love/lust statups. So its more time efficient to pick them over the earlier levels (unless the % to success is too low).
-Use highspeed to cut down on lunch and dinner (from 1 hour to 5 minutes) and the movies (eva, some finishers of other anime)
-Use AT field before cosplay sex, to save your motivation
-use cosplay sex at the end of the day just before sleeping, that gives you a big bump while it doesnt eat into your time
-for the first playthrough you can just spend all day watching anime to unlock as much powers as possible, you probably wont unlock the cosplay costumes though
-MIX might seem weak at first but its actually pretty great, have foreplay/sex just before lunch/dinner, then use MIX on lunch/dinner, and the stamina boost from lunch/dinner allows you to have sex again.
Endings:
love end: 500 love, nothing else
desire end: 500 desire, asshole level 3 (no idea how to to get it to level 3 to be honest)
aniota end: 400 love and desire, 500 otaku, cosplayed eva
moeota end: 400 love and dsire, 500 moe, cosplayed love life
fujoshi end: 400 love and desire, 500 fujo, cosplayed utapri
idol end: 400 love and desire 500 idol, held dick shake event
idol VA end: 400 in all stats, 5 cosplay sex events
true end 500 in all stats, cosplayed anohana
Overal interesting game, the time limit is pretty tight. Only problem is that some stat increases and unlocks are just impossible to understand.
