I guess my team would be:
Tamao by by Nyan Kiryu: I thought Tamao was cute and I love how she plays, so I use her.
Taiga by Kohaku: At first I didn't use her too much, but over time, The Plamtop Tiger has really resonated with me. Plus, her combos are fun to pull off.
Kamijo Touma by okita: He can do big damage and he's really fun to use. Also, love his Imagine Breaker.
Hina by oyaji: I love how her zoning game needed some thought as her meter prevents her from mindlessly spamming. Also, she doesn't have a traditional crouch. Plus, she's cute in a evil way.
Ingrid by Sennou-Room: I've always been a fan of her design and moveset. Plus, she's cute
Vegeta by Choujin: I'm a long time fan of the Dragon Ball franchise and Vegeta was always my favorite. I fell in love with how Choujin's Vegeta controlled.
Ayane by ZSM: Possibly the only Vangurad Princess character I enjoy using, I like her playstyle a lot. Also, she's cute.
Yuka by Nyan Kiryu: While I do prefer Tamao, Yuka is still a really fun character for me to use. Plus, she's cute as well.
Rentaro by Kohaku: He definitely grew on me over time. Like Taiga, his combos are fun to pull of.
Patchouli by Ricepigeon: My favorite Touhou character and Ricepigeon's version is quite fun to use. I'm gonna sound like a broken record, but she's cute as well
I got some other characters that I use, but these are the main members of my team.
