The simplest way is to attend events and make yourself known. The more events you attend or the more money you spend, the more likely you are to leave an impression. However, I know that's not the method the friend is asking about. They don't want an idol-fan relationship, but a closer relationship than just friends. They wouldn't mind sleeping with her if it meant more...
Okay, let me answer this question seriously!
First, you need at least basic Japanese conversational skills. If you can only communicate with the actresses in a completely different way, it's impossible to take the relationship to the next level. Secondly, you must become someone the actresses like. You might need to be very handsome, very funny, have a bulging wallet, or a long foreskin… In short, you need to be their type first!
So, what kind of type do actresses like? Coincidentally, the recent scandal involving Hoshina Ai has been making headlines, so let's take a look at the male host she's supporting:
His name is "Shiina Reijin," and he's a fairly famous male host. Just like I mentioned in my post about Hoshina Ai, a group of actresses who earn money go to male hosts... They go to host clubs, and what they like are these fair-skinned, slender male hosts with a touch of aristocratic air—
This particular host happened to be on TV, so let's take a look at his attire and manner of speaking:
Please skip to 4 minutes and 58 seconds into the video to see the beautiful Shiina who broke Hoshina Ai's heart: Honestly, his style isn't my cup of tea, but it probably explains why Hoshina Ai revealed she earned money to spend on him—his entire outfit cost 3.93 million yen (approximately 1.1 million NTD)!
The fact that she would date someone like this and even self-harm shows Hoshina Ai's taste. And frankly, quite a few AV actresses like this type of man. If you understand Japanese, you might want to observe the actresses' preferences. If you have the chance, of course, try your best; if not, don't waste your energy.
