I'm free anytime this week actually.
Oh btw I finished the game. The final battle was scary hard...until I realized something. Zukki has the most awesome ability ever. Just keep her in your team and feed her TP boosting items, and then use her second ability that stuns the enemy for 3 turns. Rinse and repeat while everyone else is busy attacking. It solves the problem of Riho's Glass Cannon Ninja Status (seriously, she splits into two for half of her max HP each, which makes her ridiculously fragile....but being able to use her Moonlight Night attack twice in a turn for almost 200 damage each round? Hell yes.
Riho is my designated boss killing machine even without her Ninja-ified self. Just buy lots of Ichigo daifukus to make sure she has enough TP to go around.
Duu's best weapon (without farming for item creation!) is without a doubt the Killer Saw that drops from the purple bug-like plant enemies that appear around Hiroshima. It gives her the ability Killer Saw, that absorbs HP from the enemy. Pair that with an Atk Up and she can basically heal from anything. Her stat down moves can make a difference (atk down can be a life saver), but you're better off straight up attacking with Duu. Killer Saw is the best thing ever.
Ayumi gets outclassed the moment you get Riho when it comes to boss battles. In regular fights Ayumi is arguably better than Riho because of her final Dance command that boosts her agility and gives her two extra moves, the Daishi Mach Punch and I forgot the second name, but basically the first is single target and the second is multi-target. Hits for around 40~ damage (I maxed her level at 25, gave her the best weapon I could). But Riho's Moonlight Night (costs 15 TP) does 80~100 damage depending, and her base attack stat is higher than Ayumi's, even when she's a few levels below her. Daishi Attack becomes basically useless in the final stages of the game unless you can boost her attack, but it still doesn't do as much damage as a single Moonlight Night from Riho. I pretty much stopped using Ayumi after Riho joined the team.
Harunan is worthless in the final battle. Her Silence move doesn't work on the boss, so you're better off using stun attacks by either Zukki or Fukuchan. But the second-to-last boss battle works for her, because Silence DOES work on the boss, not that it really matters because that boss's hit-all isn't magical in nature orz. Her only use is as a second healer (the party member switch skill is invaluable), and you can teach her the skill Reborn which is like an instant Revive with full HP. Harunan has the highest MP of them all, so it's a good skill to teach her since Reborn costs 20 MP.
Maachan is hands down your lifesaver. She IS your healer, much better than Harunan, because her single target heal spell (Pokepoke, 3 MP) heals for 30~40hp, and her multitarget heal spell (10mp) heals for 40~ hp each. I don't even bother to use her to attack in a boss fight because I rather conserve her MP for much needed healing. That and her Special, English Education, lets you heal your entire party for 40ish hp each for only 3mp. How much do I love thee Maachan? Let me count the ways.
You get Eripon too late to make any difference except to swop in to soak up some damage, since she has good stats despite being lower leveled. Her special, Golf Swing, costs 50 TP and has a higher chance to miss, but it does about 100+ damage if it connects. After you beat the second to final boss, you can equip her with a weapon that gives her an additional attack skill, but it doesn't really matter since I don't find it very effective overall. She has no passive skills that make it worth the trouble of putting her in the team unless you don't have a choice (aka, everyone is knocked out)
Fukuchan, oh Fukuchan. Her spells are great. Like, seriously great. Def Up for entire active party? Yesss. Regen for party? Uhh....not as useful. What IS very useful though, is her passive ability, Sexiness.
Chance to stun an enemy she attacks. And she has decent attack stats, not very high in particular but not too shabby. Stun, in any case, is totally worth it, even if it doesn't always activate. Then again, when you're fighting a boss, double Def Up can save you a lot of pain and chance to stun is always good. Additionally, if you can get her up to 70 TP, she has a skill Fukumura Lock that also inflicts Stun for several turns. But I rather use her TP for Mizukick because someone else is better at the whole stun thing...see below.
I wasn't very impressed with Zukki when I first got her. Until I paid attention to her skillset. Her second TP move Kamakiri (costs 40 TP) stuns enemies for 3 turns. Totally a worthy investment. Zukki's Kamakiri with Riho's Ninjutsu makes for a very effective boss killing teamwork. SayaSuzu forever! Plus Kanon has the highest HP total of the entire group, and the highest regular and magic defense, which makes her very very durable...good for absorbing damage and building TP for the inevitable Stun strategy with Kamakiri. Her other skills that inflict Agi Down is also useful especially for speedy bosses, and Butterfly restores MP to your party....but I prefer saving her TP for Kamakiri.
Riho. Oh Riho. Fastest member of your team (except for Ayumi when she's on steroids...I mean, her Agi Up move), decent base attack, but what makes her awesome is her Moonlight Night single target move, which makes her THE boss killer (assuming you keep her nice and healthy). 90+ damage every turn? Yes please. And she gets even better if you max her TP gauge to activate Shuwa Shuwa Pon! It opens up 2 commands, one that gives you max TP for the cost of 10mp, and the second one is just a game breaker if used right. It halves Riho's HP total, but allows her to attack TWICE in one round. Look at it this way. 10mp to buy 100 TP, 100 TP to double attack turns, 10mp to max TP again. Spam Moonlight Night ad infinitum. Paired with Zukki's Kamakiri move, you never have to fear a boss fight again. They can't even damage you. But if you want to conserve TP items, just her regular mode (not the jazzed up Ninja Sayamaru mode) with her Moonlight Night every turn is enough to slowly chip away at those bosses. Which is what I did many a time.
But yeah....this has been a fun game. On a final note, from Harunan...
IT'S CHOCOLATE. NOT BROWN. CHOCOLATE!!!
