For these events, only 2 things are really important:

1) Your SED or Seduction rating. This is basically the seduction rating of all the girls you ever collected (and leveled) put together. A new player won't have a very high SED Probably somewhere between 5k and 10k. For this specific event, you can get "slayer cards" from the Event Gacha (and also one from normal gacha) which multiply your SED. These multipliers are multiplative, not additive. So a 1.6 multiplier and a 1.2 mulitplier result in 1.6 * 1.2 = 1.93. Leveling these slayer cards increases this multiplier once every few levels. The maximum multiplier for all phase 1 and phase 2 slayer cards combined is usually between 40 and 50. So if your normal SED is 10,000, then it could get boosted to roughly 400,000-500,000. Not something a new player would easily accomplish, since leveling all those cards to 100 during the event would be near impossible..

2) Your Focus. They're comparable to our raidpoints. You get 1 Focus every 5 minuts, each focus is a weak attack, and 6 focus is enough for a full attack.
If you can kill the bosses with 1 weak attack, then 6 focus means 6 dead bosses. But, for a new player it's very normal to require multiple attacks to kill a boss. Making it much harder to reach 1 million points, simply because you need more focus per boss.
