where did you learn how to use he bow?
and how did you get scene 13 -15?
The bow is a quest item, not an equippable.
Re: Scenes: Only the section at the bottom right corner where only 2 / 3 of the scenes are obtained were unlocked via the first two quiz daughters. Normal scenes 1 - 15 were all from normal progression of the story.
If anyone bothers going through the story, you'll find it's an absurdly easy RPG where most stat boosts are gained via equipment, and once you get the latest version of weapons of whatever region you're in, most battles will be over in one or two turns. The only real searching you'll need to do is just for the quiz coins, since treasure chests carry minor stat boosts or free equipment which you can easily get from the shops with a little bit of money farming.
It simplifies things, but this really just means that this game is mostly getting from point A to point B, and then progressing the story just means getting from the new point A to a new point B. As long as you don't run away from
too many battles, your levels will hardly be an issue. Bosses are more of a battle of attrition than actual challenges since Mei's healing skills are plain OP. I also hope you like seeing enemy encounters because it gets truly obnoxious sometimes where you move for less than a second before you get another encounter, and the no-encounter equipment is only given to you at the
very end of the game.
TL;DR: This RPG is really easy as long as you don't escape from too many battles. Get updated equipment whenever possible and you'll be fine. I hope you like going from point A to point B a lot because this RPG is essentially that. Scenes 1 - 15 are unlocked via story progression. Any other scenes are unlocked via quiz daughters or minor side quests.
