Bro, literally unless you bought it original, you most likely got the game from this page and obviously since the thread hasn't been updated on the latest page, since even the mods don't know whether to update it or not because it's not "really" translated, you had to be on the lookout and reading at least the most recent pages, so if you have problems with Mtool to be able to play, simply use ITH + Translation aggregator (I use that combo and I've had 0 problems and I'm already on the third route) or any of the other methods or options that have been shared.
And bro, I share your feeling that this game got more bloated than Naruto filler in part 3, but also as a response to this, Torotoro put in the secret stones, which you have to use and even make any character you have, regardless of whether you ever made Labyrinth or not, a monster with stats from hell and if you still don't want to have to farm stones or their materials to create them, simply use cheese, in the translations part, open the weapons, armor and notepad files simply write in Japanese in the search option the names of the characters you use (if they are main characters) and hit search, it will take you directly to the name and ID of the most broken weapons before Labyrinth that you can have in the game and with that, even if you put bad stones in the 3 slots, you don't suffer as much even in paradox difficulty.
Or, if you don't want so much trouble, simply if you have touched the third route already, then you´ll have obtained large medallions, with having 3 of them the doors of the world will open, since if you go to the castle of medals, with the king (I don't know what the queen gives or if she gives items, I haven't discovered where she is yet) you get a universal set for any character that is the third best in the base game without items in the labyrinth, but of course that set each piece is worth many medals, what you would simply have to do is download cheat engine, open it, link the game, type without touching anything in the options 3 * 2 + 1, hit search, exchange a candy that is worth 1 medal, change 3 * 2 + 1 for 2 * 2 + 1 and hit next scan, do the above again until you are in 1 * 2 + 1, then in the search list there will only be one result, double click or drag it down in the white box that is there, then left click and in the options that come out, click on change to hexadecimal and finally, from the sequence of numbers that it changes to, leave the last 2 numbers on the right untouched and after these, right-click on them and an editing box will appear, delete the 2 zeros that are before the last 2 and write AA and click on ok, finally just check the box for the process that is there and that's it, you can buy anything from this store, which apart from the set I would recommend that you buy the MP and SP reduction stones, so that you can make chains easier.
And that process you can use for anything in the game, even if you only have a single object of a type, although for that process it is a little different, for this you simply apply the fundamentals of the above, but in the maid of the pocket castle, depending on what you want to increase, when you give it the option to store objects, choose the type and in the list that comes out of objects that you have find the object that you want to increase, to this only object you pass it to save and without leaving the menu and with the cheat engine you write 1 * 2 + 1 and you press search, then you return your object to your possession and without leaving the menu ever, in cheat engine you change to 0 * 2 + 1 and you press next, you do again the same thing as before passing the object and write 1 * 2 + 1 and you repeat everything until finally you have a single result and important, the only object that you have of that type was stored with the maid, when that is the case do the same thing as before to lower it to the white box, see it with hexadecimal and edit it with AA and that's it, when you want to move the maid's items to your inventory you'll see that she has an infinite number of them and you can simply take as many as you want, and another option is to use the original process I mentioned, apply it with the seeds to the characters you want, use an auto-keyboard and let it increase the stats as much as you want.
Anyway, I hope I've been able to help a little all those who arrive and only see walls in this current final part (since who knows what they'll do if they really do the fourth route in a DLC) and are using either the Raw 3.01 game (recommended, since using the version with translation drives automatic translators a little crazy) or don't want to touch anything in the version with translation for fear of ruining something.
Bro, if you didn't read the intro of the third route well, from there they make it clear that Torotoro was inspired by the most recent Zeldas and you can go wherever you want, even to the final boss from minute 1 but of course, being unable to do so and in fact, if you do, getting one of the 2 endings that are in the third route, which is the canonical bad one, with the destruction of the world (I think, since from what I understand, if you don't do events before going against X or Y boss, then Luka has to use the deus ex machine of the power of chaos and every time he uses it he gets closer to himself causing the end of the world) given that, they put the worst patch for "what if I fight with only a knife against a destroyer of worlds and still win?" instead of putting an invisible wall of "X talking to Luka: Luka don't be a lunatic, first we need to recruit more people to be able to face a destroyer, let's prepare first".
What's more, now that I think about it, what a missed opportunity to make reference to Elder Scrolls with the mission of killing a powerful creature with a fork, although by reference this game would even make captain america come back from the dead and give him a pat on the back.
