No-appointment Gals Olympos (JP) - Full Playthrough (All Kills, No Lost)
The original recording of this video was 3 hours 2 minutes, even though I skipped as many cutscenes as possible. However, a lot of segments have to be fast-forwarded since they show basically the same thing, mainly due to the long loading times and animations between battles.
There is a report card after the credits (that I showed at the end of this video, as well as video's thumbnails). This report shows how many unique cutscenes that manage to be triggered in the playthrough. The big number near the top says "number of battles = 53". However, each girl has unique cutscenes, and for most of the time, only one cutscene can be triggered before a battle. By manual counting, I found out the total available cutscenes are 230 scenes, meaning it would be impossible to watch all of them in one playthrough, even if you manage to make a note and only trigger events that you didn't watch before.
"All Kills" means that I managed to kill all opponents and didn't let even one of them escape the battle. This would speed up the progress since the enemy players would take extra damage when the summoned gals are killed. If the summoned gal manages to escape then the enemy player only takes about half of the amount of extra damage. Therefore, you need more battles to defeat the enemy players, which would take more time as result. For instance, if an enemy player could be defeated by achieving four perfect kills, then it would take about seven or eight battles if you let all summoned gals escape.
As another note, the big number near the top says "number of battles = 53", but by manual counting again, I managed to unlock a total of 56 unique scenes from those 53 battles. Therefore, there seems to be what I called "chain of scenes", and I speculated that these extra scenes can be watched if you choose to "wait for a moment" during those scenes that offer this option. I didn't bother with this since I skipped all the cutscenes.
After winning the battles, I always put the extra stat points to Critical. There is no information that I can find on the internet, but I believe that Critical affects the percentage or threshold of how the character can trigger their special attack. And special attacks are guaranteed to one-hit kill the target if they manage to hit, which means they will end the battle soon, and possibly decrease the number of necessary battles in order to defeat the enemy players.
