1# Okita: I love tsunderes, and although he had the whole "I'll kill you" thing in the beginning, his endings were just so sweet. His bad ending also, was definitely worth playing since it was just such a tear-jerker ): I just loved his route because of how much he changed for the protagonist, and it's the only one that actually solves the whole "twin" incident (the other routes just completely left it out...)
2# Kazama: Yes, I love sadistic/tsundere guys LOLOL! Although I thought his story was so short/ended abruptly, I still really liked his character. Although he was straightforward/blunt, he cared about Chizuru in his "own way". He wasn't as evil in the other stories, so that was a definite plus. I just wish his story was longer, or didn't start so late ):
3# Harada: His story was the happiest ending, and it was just so sweet/happy throughout. His dialogue to her in their "romantic moments" was just... wow. I thought it was also really cute that they shared the "same dream" and how it came true in the end. For him to choose her over his life long best friend, that just spoke so much about his character.
4# Saito: In all honesty, looks wise - then he captured me first. Although I did like his story, he was just too unemotional for me, and half of it was just his "journey to becoming a bushi/what a true samurai is". I felt that there wasn't enough romance, and their relationship developed out of nowhere :S He was definitely very cute though, when he had his "blushing" moments ^_^
5# Heisuke: He was very adorable, but he just didn't stand out to me compared to the rest. Although when he had his "clothing change", he turned out to be so handsome. I think out of all the guys, he realised his feelings for Chizuru first, and it was really sweet how far he went for the protagonist. I found his confliction a bit annoying for my taste though, since she'd keep telling him his life was important - and then he'd agree, then change his mind :/
6# Hijikata: I did like his character (he's like the prettiest guy in the game... lol) but I felt his story was just so angsty, dramatic and sad for 90% of the story. Practically everyone died, and it was just so heartwrenching. It was just too dark for me, and the story was just so long >_< Although I did like the ending, I felt like there should've been more, after how much they went through </3
