These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Mad Dog in Sundown's chapter, though this may be intentional. Defeating him on the second fight removes an additional scene from that chapter's ending.
O-DI-O from Pogo's chapter is really simple if Bel learned her singing attack.
OD-10 in Cube's chapter can be easily defeated by standing next to him and using High-Speed-Op and Upgrade, Cube will counter each time he is attacked, and become stronger with each heal. Eventually, he can do more damage than the boss has HP.
Depending on how you play through the chapter Oboro's Final Boss can easily be killed or be ungodly hard.
The final battle against Straybow in Oersted's chapter. While he has improved some since the fight at the beginning of the chapter, he's still relatively weak in comparison to the bosses fought before him.
Level up Sundown enough in the final chapter, and he learns an ability that can usually do 999 damage in one hit, making almost every fight an Anti-Climax Boss.
Odie Oldbright (much like every boss in the fighting chapter) has no defense against Abise-geri. If you're lucky and it turns him around every time, he'll never even get a chance to hit you.
Alicia can be seen as either two ways. A) Always in love with Straybow and Oersted was just reading too much into context. Or B) Shallow typical ditzy princess who only crushed on Oersted after kicking ass in the tournament and was easily seduced and manipulated by Straybow, whom simply wanted to ruin Oersted out of hate either way. Depends entirely on how much you read into things really.
She can also be viewed in more of a sympathetic light, in that she truly did have feelings for Oersted but was emotionally manipulated into falling in love with Straybow. If you buy into the idea that Straybow was the one behind her kidnapping in the first place, this seems like a perfectly viable interpretation.
Oersted himself can also qualify. Think about it this way: once he became Odio, he said he would make "humanity see the folly on their selfishness". Did he really snapped at the end, or he was actually doing what he believed was the only way he could help humanity? After all, once you take control of him you see he could trigger Armageddon very easily all by himself.
Cube's chapter only has one required boss battle, and it doesn't have a single Guide Dangit. That doesn't mean it's boring or that you can't die in it...
Sundown's chapter has a total of five battles, of which one is optional (and eliminates one of the others if you choose to fight), three are laughably easy, and one is against the chapter's boss and can be made significantly easier depending on how you set the traps.
Cliché Storm: One way in which the game suffers is its short chapters - the plots are general and predictable, and you tend to know exactly what you're getting from them. Whether that's a bad thing is up to your interpretation, but it gets subverted near the end of the game either way.
Fan Nickname: "知力25" (INT or IQ 25) for Masaru. Because his base IQ will ALWAYS be this. Parodied with Cirno crossovers.
in ''Touhou A Live, she's the star of the similarly styled chapter.
Fridge Brilliance: It seems rather jarring (although not unexpected for RPG standards) for Oersted a.k.a. Odio, the friggin Demon King, to be beatable. However, recall Uranus and Hash's words: "As long as there is someone who believes in you". The little kid does in fact still believe in him, even after his death. No wonder Odio is beatable. He wasn't being hated enough.
The Cola Bottle from Pogo's chapter can become this in the final chapter. Just make sure to equip it to Pogo as an accessory before his chapter ends, and it'll carry over to the final chapter when he joins your party. The Cola Bottle is an infinite-use item with an attack that can deal 999 damage to almost every minor enemy in the game (and even some bosses!). Needless to say, the final chapter becomes a breeze with this in your arsenal.
In Pogo's chapter, there's "Laa Laa", an attack Bel learns at Level 7. Take an hour or so to build her up before examining Zaki's firepit, and you can one-shot O-DI-O. As in the chapter boss.
Goddamned Boss — Voice Heart. After encountering him several times in an extra dungeon, you will want to scream "JUST LEAVE ME ALONE." It's quite gratifying when you get to tell him off and kill him at the end of the dungeon.
Cube's chapter, once the Behemoth gets loose and things start to go to hell. The tense music doesn't help.
That weird person(?) who runs away from Oboro emitting some kind of horrible roar.
One attack used by the final boss is also accompanied by a horrible wail. The visuals make it far creepier, too. That would be "Saint Alicia". The aforementioned visuals are that of an angelic-looking female figure hovering over the target, and then quickly melting into a horrifying hag with a mouth of fangs. The worst part of it is the name. Saint Alicia. Oersted is so consumed by hatred that that is how he sees his once beloved Alicia.
In the Final chapter, the kingdom that the Medieval chapter took place in is eerily quiet. What happened is hinted in a number of places, and then all but outright said in Akira's secret dungeon: Everyone's dead. They either died during the events of Oersted's chapter, or were killed by Oersted as Odio. Even the little kid who still believed in Oersted.
The prelude to the Death Prophet in the final chapter. You're just minding your business, probably running away from battles when things go south. And suddenly, after retreating, the music stops and an ominous message like the Grim Reaper warns you that death awaits those who run away too much, and starts counting down to zero every time you run away. When the countdown reaches ZERO... it comes to you. A black panther monster that can easily turn you into stone. Unless you're the type of keeping count of how many times you run away, the Death Prophet's warning comes off as chilling and shocking.
Amongst many, die while piloting Buriki Daioh. Akira and Matsu revive as spirits and Matsu says "You Bastard!" to Akira before the player returns to the load screen, feeling a lot like the You Bastard in question.
The Kung Fu chapter. The Master takes in three bright, promising pupils who all show signs of being inheritors of Shin San Ken, and then two of them are murdered by Odi Wan Lee's goons. Even worse is that, once you know how the game chooses which ones live, it's basically you deciding which ones die. Go ahead, try not to feel bad when you replay the chapter, with that knowledge.
O-D-O has Bite, which can do massive damage to anyone in the party.
Ode Iou has Poison Serpent Whip; while it doesn't do much damage, it covers almost the entire battlefield in poison spaces. Also, Drink Blood is pretty strong and heals Ode Iou.
Odi Wan Lee has Kuang Zhuan Yan Wu, which can easily kill the inheritor when you face him.
O. Dio has Gatling Shots, which almost always does enough damage to result in a One-Hit Kill.
Odie Oldbright has Acro DDO, which can kill Masaru in one hit. Two hits, if the player's lucky.
The Inka Kuruu Odeo has Liquefied Human Curse, which does random damage, but normally does plenty.
OD-10 has Driveback and Driveback-Counter, which deal tons of damage and create electric panels; however, he will only start using them if you cast Info Research on the middle of his sprite to change his graphic.
The Demon King's strongest attack instantly stones anyone hit by it. This can, however, be cured with Uranus's healing move. God help you if he gets stoned.
Pure Odio has Cancel Ray, which instantly disrupts any attacks you have planned, but he and Illusion Odio also have Life Eraser, which will stone you for sure if you don't have the Ariel Equipment. Pure Odio likes to use Life Eraser (which also heals him for any damage done) after every move you make, which means hurting him is nearly impossible.
Optional boss Amakusa in Oboro's path has Electric Barrier, which deals 120+ damage and surrounds you with electric tiles. Oboro has about 160 HP if you've killed everyone in his path up to this point. And Amakusa likes to use this attack twice in a row. (This is not a Bonus Boss, but rather one you must fight if you take a specific path through the chapter.)
King Mammoth. (and Lord Iwama, mostly if you attempted a pacifist Oboro run.)
When it comes to required bosses, Max Morgan from Masaru's chapter is an utter bastard. If you slip up just once, he'll kill you in three hits. (And remember, Masaru has to take hits in order to learn his skills!)
Gynophobia, the second-to-last boss in Oersted's chapter. Giving a boss two attacks doesn't make her fair when one of them heals her for all the damage she deals and the other puts you to sleep. And the one that puts you to sleep has a massive range. Even better? You fight this boss alone.
What Could Have Been: The game's director Tokita has always wanted to remake the game with modern technology, if only enough people wanted it to happen. Sadly, in comparison to its Spiritual Successor Chrono Trigger, most jrpg fans in Japan don't remember that this game existed.
Cube. And depending on your temperment, Yuan from the Kung Fu chapter.
Oersted/Odio could count, too. Granted,he is the main villain of the game and wants to punish all of humanity and ruin many people's lives, but considering all he went through that led to his turn to villainy, it's hard not to feel at least a little sorry for the guy.
The Xin Shan Quan Inheritor regardless of who that ends up being. They come to lose their entire adoptive family-in Li and Sammo's case, the only family they actually have (Yuan at least still has his grandmother)-and their beloved Master, who taught them all his secrets and gave them a better life dies in their arms after giving them some last words of encouragement. At the end the Inheritor is left to rebuild the school and keep training a new generation of Xin Shan Quan students alone, but with the knowledge that the Master and the other two students are watching over them.
