Just finished my 60 day run with ss rating. Honestly not really worth doing unless you want the unlockable that gives Graffiti pen(adds graffiti to bodies). If you do the run, choose to go to the tutorial or intro(cant remember which choice it is) and fuck uruha infinitely. This will give you exp, pregnancies, money etc for the rest of the run. Each level up gives 1% increased impreg chances which makes the run easier and the money can be used to get the 5% impregnation skill from the shop. You might be tempted to get the gender change item but don't, it doesn't work. If you are unlucky with pregnancies you can also just save scum&reload before birthing to reroll.
If you don't want to grind exp, you can cheat engine it as well. Xp on this engine is double so if you cant find it, put your current xp*2 in the engine. EG. 5234*2
2 other things:
1. In the gallery(at your computer), you can look up characters schedules and find where they are each timezone. The only incorrect ones i can see are asari toyoda, it says she is only in the fields but she is in her house in the second timezone and in her bedroom for night time and Cassandra, the third timezone isn't translated but its in a bedroom upstairs in the b&b.
2. Hassaku has no hints on where to get her and someone mentioned 5 conversations, there is actually only 4 you need to find. They are: a student in the school bathrooms during midday, a red head guy just below the b&b also midday(i think), a guy to the left of the bus stop(its just above the sea location on the bikie) and a guy to the right of the bus station. After this, the mc gives a prompt for the 5th conversation which is with the village chief.
