So it's Saboten turn next. It's will be a couple more until I can give verdict from experience so for now... paper only again.

Saboten is the girl who got lots of rebuff through out the course of the game lifetime. Back then she seriously lacking in many departments that she was branded 'meh' as no one really thrilling getting her. I don't know how things are in Nutaku for her now but in DMM as is now? I think Saboten is one of the most powerful boss killer in the game, that is if under correct composition and support. Now let's take a look at her, the girl who is calm and cool as freezer outside but has a burning passionate inside. (Or as she claimed)

1. Raw stat: Noting so exciting except for her defense. 3500+def is definitely high end and it will help her a lot if she ever gets counter and while her HP is on a low side, she won't fall down TOO quick. (Emphasis on 'too' as she got zero survival ability) The worst part though, is her atk which is low for total offense oriented character. Such a shame...
Grading: C

2. Skill: Sabouten has the highest skill activation at 46% top. Even at lv.1 her rate is similar or even surpass the majority of the girls at 36%. The damage after the latest buff is awesome 5x. Considered how low her atk is this skill is godsend to help Saboten goes 'ORAORAORA' on pests. Combined with her abilities and Saboten has chance to dish out 10x on enemy every turn. And well... what to say besides YES?
Grading: S

3. Abilities: Her atk buff is nothing to say much, 20% buff is very average but definitely not bad. Crit chance and crit damage duo are always needed synergy for crit team. 15% chance is tad low but considered that crit chance capped at 80% and girls with crit buff is like, lying around everywhere now, it's so easy to form a team. 40% crit damage is currently at top game and definitely welcome since this one doesn't have max capped.
The real juicy part of her is the 60% chance to double act. Like I said in skill part, her low atk got covered by this awesome skill+ability synergy. It's 5x at worst and 10x at best when she's under enough skill act boost, and it's much easier than most girls with her high natural skill act rate. Her best spot in the team is obviously the back, or at least after sweeper.
Then there's a completely gimmick part that I don't know why it's here. 30% shine crystal drop rate plus for team is nothing amazing and it's not even worked for whaleship, only for party Sabouten is in. At least her attack got many hits so it generate lots of shine crystals but well... it's nothing to be excited and there's a lots of abilities that would aid her better. One step short from perfection.
Grading: A-

Final verdict: Saboten is strong girl with beastly skill and a great ability to sync with that. She is, however, very dependent for support whether it's atk buff, damage buff, skill activation, or crit to function properly as boss killer. 10x damage is sometimes inconsistent with 60% chance to dish this amazing damage out. Once you geared her properly however, not many bosses can withstand her oraora onslaught. So here, A for her deeds. A little bit to A- side since she needed lots of supports and can't carry the team alone though.

Extra: Not much to say about her, I like her for her skill animation mostly rather than any waifu factors. So well, this is the first thing comes to my mind when seeing her skill.
