ultimately, i really only liked shiraishi's route, and found myself rushing through everyone else's. shiraishi IS very cute, though.
my thoughts on each LI:

- enomoto: feels like five different gimmicks in one character. would be cute if he lost the fake eyepatch. not very memorable. i think it's been like a month since i played his route and i can't really remember a single thing.

- sazasuka: WORST BOY!!!!!!!!!!!!!!!!!!!!! sucks so bad. wish i could delete him permanently from the game.

- okazaki: felt like his route would have been a bit more emotional if ichika could have been a tiny bit crazier while romancing him. two crazy people feeding off each other. as it is... well, i guess he's cute enough. i'll never forget his words of wisdom:
"Yep. That's right. Pillows are suuuper important to people living in a modern society. Yeah. I'd love to average 24 hours of sleep a day."
so true!!!!

- shiraishi: my adorable quirky little catboy. wish i could introduce you to ffxiv. you'd have so much fun there. ichika is at her best in this route.

- yanagi: boring. too perfect. the villain in his route is much more interesting, and to be honest, i wish we could have gotten more of them. felt so disappointed because both ichika and yanagi are so idealistic and naive in this route! their righteousness is kind of irritating, to be honest. let me romance the villain, instead!

a funny thing i just remembered is all the people on r/otomegames saying this game has so much commentary on current events. what? no, it absolutely does not. i felt like the writers were all sitting around and then someone said "what if cults........ could be sexy?" i don't think it gets any deeper than that. but it was a fun little VN, all the same. will probably pick up the sequel soon.

loved this game. the main story was gripping, and i fell in love with the side characters: hamura, higashi, saori. just loved them. the mc, yagami, was harder for me to get a grip in - he's noticeably much more bitter than the previous rgg heroes - the guilt he's carrying around with him makes him somehow seem like more of an adult than kiryu or ichiban. but maybe that's because the tone of the story feels much more serious than the mainline rgg games.

things i did not like:
- no karaoke :( and one of my friends told me that takuya kimura is literally one of the most famous singers in japan! i guess it would have been too expensive to have him singing in the game, but still. how am i supposed to understand a character if i can't see how they imagine a music video starring them and their friends?
- the combat felt a bit clumsy to me, but maybe that's just me.
- mafuyu, unfortunately, really does nothing in the game. she has one of the most beautiful character designs in the entire series, but all she does is show up and look worried occasionally :( sad!
- no way to tone down the random encounters. it got to be kind of annoying at around the middle of the game, where i just wanted to focus on the main story because i was so enthralled.
- don't like the dice and cube minigame. yagami looks stupid with the glasses. sorry. actually i don't like his outfit either. he looks better with the lawyer get-up.

things i did like:
- whatever was going on with hamura. wow

- i loved the characters. ichiban is so charismatic! and i loved saeko and adachi, specifically. they all have good reasons for following him. i especially loved seeing the little dialogue that pops up whenever you're walking around town - it really makes them feel like a group that enjoys hanging out with each other!
- also love the fact that pretty much everyone is unemployed. except for saeko, who is probably using up a crazy amount of vacation time for this.
- i liked the story a lot - very compelling! i had some issues w/ a few things but i won't go into it too much. i don't see the need to nitpick.
- the gameplay could be improved a little. hopefully they polish it up for the sequel. i don't like how enemies move around, which means that some of your AOE attacks don't hit them! i didn't like the sudden difficulty spike in the last quarter, either.
- the music was not as good as the other yakuza games i've played - namely yakuza 0 and kiwami. 0 had an AMAZING soundtrack and unfortunately, this just isn't as good. the dungeon crawling music was so, so, so grating.

all in all, i would recommend this game!
