It's so cool to see people using characters despite the wiki currently giving unflattering reviews of them (although I suppose that will change soon). Here's a summary of my thoughts on some of the characters I see people are using:
Rumia - Surprisingly powerful MYS nuker, as Moonlight Ray can put up some incredible numbers. If you have a way to buff her MAG (such as with Iku or Ran), you can expect Demarcation to become a rather powerful healing spell too; maybe not quite as good as Reimu's, but still quite servicable. Her MAG growth is actually the same as Reimu's, but Rumia levels faster, so the worse formula on Demarcation can still be worked around. I've gone all-out MAG with her, and am still not disappointed with her as of 27F of the Plus Disk. In fact, I've been using her more and more often as I get later into the game. You can see her in my later boss videos healing for 15k HP at level 240 or so, thanks to Iku.
Wriggle - She impresses me for being a damage dealer that never needs to put any points into her offensive stats. This lets you spend all your level up bonuses on HP, DEF, and MND, turning her into a durable character with excellent status resistances as well. Her poison damage isn't necessarily amazing, but still better than many give her credit for, as I've calculated in a few of my videos. Compared to other "tank" characters, at least she contributes way more damage than most.
Iku - Probably the #1 character on Team Unappreciated that surpassed my expectations (although they all did to some extent). When I first started using her on the team, I thought Thundercloud Strickleback was only 50%. But then I discovered that not only is it more than twice as strong of an offensive buff as Miracle Fruit, but it can be cast almost twice as quickly too! Now, all my boss fights start with Iku charging up my damage dealers by an absurd amount. There's nothing better for pumping Rumia's MAG for some strong healing. And don't even get me started on composite formulas! In my video against the 25F boss, you can see Orin doing 200k with Blazing Wheel unbuffed. After a single Thundercloud Strickleback? Well over 400k damage. How many 40 SP, 60% post-use guage moves can boast that huge of a damage contribution? But that's not all; I've also finally realized that Iku is an absolutely amazing MND tank as well! She's got a MND stat that rivals Tenshis, but with better HP to back it up! For those of you who are just starting to use her, I'd recommend going all-out MND to turn her into a magic wall as solid as Patchy. She doesn't need MAG if you're just using her for debuffs and Thundercloud Strickleback anyway. And believe me, that's all you'll need for her to be worth a spot in your party.
Reisen - If Iku was the #1 biggest surprise for me, Reisen is #2. When I first played LoT and read the wiki, I thought Reisen sounded like the absolute worst character in the game. A debuffer who only debuffs 15%, has poor damage formulas, and mediocre growth rates to boot? How does anyone expect to use her? Oh, sure, she's got a 40% self-buff that raises all stats, but how could that possibly save her? No one ever seemed to use her, so the info on her post-usage guages was missing. Then I was forced to use her for Team Unappreciated, and cast Grand Patriot's Elixir for the very first time. What. 83% post-usage guage? That's insane! Right now in my party, she can skyrocket all her stats from 0% to 97% in about the same amount of time it takes for Meiling to recover from switching out a single character! And with all those speed boosts she gives herself, her spells probably feel like they only have about 50% delay. Once she has enough SP to chug a Grand Patriot's Elixir whenever she falls below 60% buffs, she can stay in to do excellent damage while taking a few hits as well. And I still haven't even gotten to her debuffs, but honestly now, I'm already content with her damage output. In my most recent fight against Yuka, Reisen was able to stay in for almost the whole fight, and contributed about 80% as much damage as Nitori did. Given that Nitori is now a top-tier damage dealer, and that Reisen was taking hits while also adding some very useful MAG and SPD debuffs in addition to that damage, I'd say that's pretty amazing.
You mean for Mokou? Yeah, it's because Mokou's got MYS resistance.
Nope, I'm pretty sure Mokou's neutral to MYS. Her only resistance is to Fire.
