Dialogue[]

So Sayu wanted you to learn ninjutsu so that you could replace her at work...
Twinjutsu[]
- (Approach the location)
- Sayu: I'll show you my favorite skill to practice. Basically, it's an escape technique — I use it to make a quick getaway whenever the shrine maiden's after me.
- Kano Nana: *sigh* Alright, Sayu, just leave the explanation to me. This is a technique to help ninja train their agility.
- Kano Nana: When the unpredictable happens during a mission, ninja must be capable of traversing a variety of terrains.
- Kano Nana: During our training, we often set up obstacles on both sides of this stream and have Sayu make her way up the course.
- Sayu: I often slipped when I was little and either found myself falling face-first into the mud or getting battered as I tumbled down.
- Sayu: So don't underestimate this little course of ours, it's not as easy as you think.
- Kano Nana: Sayu may be exaggerating a little. With your adventuring experience, I'm sure you'll do fine.
- Sayu: Yeah, go ahead and give it a try, I'll guide you through it.
- Kano Nana: Nice try, Sayu. You'll run the course first. Quickly, now.
- Sayu: Aw...
- Kano Nana: Come now, no stalling. Give the Traveler a proper demonstration.
- Sayu: Alright, alright. Leave it to me.
- Sayu agilely comes upstream and reaches the destination.
- Kano Nana: Although Sayu doesn't usually exert her best effort, she does have strong ninja fundamentals.
- TravelerTraveler). Kano Nana: Do your best. I'll be waiting at the finish, (
- (If time runs out)
- You could not complete the training within the time limit...
- (Return to the previous step)
- (If you're out of the track)
- You left the training area, thus failing the training.
- (Return to the previous step)
- (Redo the challenge)
- TravelerTraveler). Kano Nana: Do your best. I'll be waiting at the finish, (
- (After finishing the training)
-
- (If you finished it within 30 seconds)
- Sayu: Wow, impressive. You've really got some talent.
- Sayu: If I were to rate your performance, I'd say you're like... a strong, fast mujina.
- Sayu: Anyway, nicely done. I was *yawn* ...rooting for you.
- (If you finished it within 30—60 seconds)
- Sayu: You're still a way off from my personal record, but don't worry, just keep it up.
- Sayu: If I were to rate your performance, I'd say you're like... an average, everyday kitsune.
- Sayu: A kitsune is pretty good, you know...
- (If you finished it within 60—90 seconds)
- Sayu: Ouch, that was... a little unfortunate.
- Sayu: If I were to rate your performance, I'd say you're like... a slow, arthritic turtle.
- Sayu: But don't let that bother you, more practice is all you need.
Why are you talking so different all of a sudden?
You're still Sayu... aren't you?
- Sayu: Hehe, don't mind me, I just happened to remember the words of my sensei.
- Sayu: After each training session, sensei would give me a score and encourage me based on my results.
- Kano Nana: I'm surprised you remember your sensei's words so clearly, Sayu, hehe. But don't you think your sensei would disapprove of you copying their words?
- Sayu: Hehe, no way! Sensei wouldn't be mad at all.
Where is your sensei now? Have they already left these lands?
- Sayu: Yep, Sensei said there were some important matters to attend to.
- Sayu: Sensei told me that they hoped I would become a responsible ninja while they are away. You know, the kind of ninja everyone can trust.
- Kano Nana: You remember your Sensei's words, but you sure don't seem to act on them, skipping work all the time...
- Sayu: Hey, I work hard... when I'm not sleepy. It's just that this season is perfect for napping, I really can't help it.
- Kano Nana: *sigh* The problem is that to you, every season is perfect for napping.
- Kano Nana: Anyway, you've certainly handled the training well so far. The next exercise is live-combat training. Let's go, shall we?
- Kano Nana: Considering that you have yet to grasp the art of ninjutsu, we'll let Sayu demonstrate in combat first. And this will be a prime opportunity for you to see her ninjutsu first hand.
- Sayu: Sure thing, just leave it to me. Let my example illuminate your path to ninjutsu.
- Kano Nana: *sigh* There you go again, Sayu. You know, imitating what other people say is a poor habit.
- Sayu: S—Sorry...
Live Combat Observation[]
- (Approach the location)
- Kano Nana: Here we are. Now, please carefully observe Sayu's skills in combat.
- Sayu: I'll do my best to make my ninjutsu a little easier to understand.
- (After the battle)
- Sayu: Whew, I'm tired.
- Sayu: At least I didn't get my outfit dirty... *yawn*
- Sayu: So, did you pay close attention to my ninjutsu?
- Sayu: Here, I'll teach you. First you stretch your upper body a bit, do a little wiggle... And then turn yourself into a ball, like this...
Hold on.
No need to rush.
- Sayu: Huh? What's the matter? You don't want to transform into a ball?
- Sayu: Don't worry, you might feel a little dizzy at first, but you'll get used to it.
I don't think this technique is as easy as it looks...
- Sayu: I thought you'd be able to catch on after seeing a quick demonstration.
- Sayu: *yawn* Anyway, I'm beat and need a good nap now. Hopefully I won't need to demonstrate that again.
But didn't you say that you would show me the path to ninjutsu?
- Sayu: Uh yeah, that was my sensei's teaching... Very strong and patient... which is a little too much work for me.
I'm really starting to wonder what kind of person your sensei was.
- Sayu: Strong, responsible, and kind. Sensei never pushed me to do more work.
- Sayu: Uh...
- Sayu: Actually, after hearing myself say that, I suppose Sensei was a lot like you.
- Sayu: Although you don't know ninjutsu like Sensei did, your other qualities are enough to make you my sensei.
Your sensei was also a ninja? Did they go by a special name?
- Sayu: Sure, Sensei's name was... Uh, what was it now...? Huh, I guess I never asked, I just called them "sensei."
- Sayu: I think Sensei was a ninja. Actually, Sensei never really mentioned it...
Okay... Well, how about some other qualities like their height?
- Sayu: Sensei's height... Hmm, they were taller than me. As for other qualities...
It seems there was a lot you didn't know about your sensei.
- Sayu: Sometimes it's hard to tell from just appearances... But these details don't matter to me.
- Kano Nana: Alright, that's enough idle chatter for now. If Sayu's sensei ever returns, I'm sure you'll have the chance to meet.
- Kano Nana: As for our next exercise...
- Sayu: Uh wait, I'm not quite up to it yet... I need to take a break first.
- Sayu: We agreed on a break after every two exercises, didn't we? Remember, to keep training from being too forceful...
- Kano Nana: Fine. Even if I did push you, I suppose you would end up napping on the field anyway.
- Kano Nana: Go, have a rest. I shall wait for you here. Remember, no running off.
- TravelerTraveler). I'll take you to a nice place to relax a bit. Sayu: Got it. Come with me, (
- Sayu: Whew. Finally, time for a break!
- (Talk to Kano Nana again)
- Kano Nana: You may go have a break with Sayu. It's important to recover your stamina and stay hydrated.
Break Time![]
- (Approach the location)
- Sayu: Just as I thought, exactly the same as before...
What is the rope there used for?
- Sayu: Sensei knew that I was concerned about my height, so before leaving, Sensei measured my height and used the rope to mark it on the tree over there.
- Sayu: "Nothing is more satisfying than growing." At least, that's what Sensei told me...
- Sayu: But even after all this time, not only have I yet to outgrow the rope... I think the rope is getting higher with the tree.
- Sayu: *sigh* Maybe it's because I'm not sleeping enough.
It's normal for trees to grow taller than people.
Trees should be taller than people.
I don't think a tree of this height will grow any taller.
- Sayu: I get it, and that's exactly what I told Sensei at the time.
- Sayu: But Sensei only laughed, though they didn't scold me at all... I guess Sensei had their own way of looking at things.
- Sayu: I really couldn't tell what Sensei was thinking in moments like that. Do you have any idea what Sensei might have meant?
I think I have an idea, but it is just a guess.
- Sayu: That's okay, just say it. Either way, I'm sure you understand more than me.
All trees will grow sooner or later.
- Sayu: Grow...
All trees will bloom sooner or later.
- Sayu: Bloom...
All trees will cast shade over someone they can protect sooner or later.
- Sayu: Shade...
- Sayu: Hmm, I think I understand now.
- Sayu: I love to take naps under a tree, or hide in the shade, or eat some of its fruit. This is how the tree provides for me.
I believe Sensei hoped that one day you would provide for someone in the same way.
- Sayu: I see...
- Sayu: Okay, just wait here. Don't worry, I'll be right back.
- Sayu swiftly fetches a pile of fruit and returns.
- Sayu: These fruits are for you.
I think you're taking this a little too literally.
Seems you haven't grasped the deeper meaning at all.
- Sayu: No, no. I get it now! Uh, how should I put it...
- Sayu: Sometimes I think that the Shuumatsuban is more trouble than it's worth. Everyone's trying to keep me from getting enough sleep and growing taller... Sometimes I wonder why I even bother sticking around with them.
- Sayu: But every time I think about it, I can't help but remember Sensei's smile, and then I think of this tree, and my Vision.
- Sayu: Someday, this tree will also be shelter for a kitsune, or some other animal. In the same way, someday, after I've grown nice and tall, I'll be protecting someone with my ninjutsu.
Which is exactly why you should take your work more seriously.
- Sayu: I know...*sigh* Sorry. I guess I was hoping that I'd grow faster, and then I could work hard. But it seems that I've already spent too much time trying to grow...
- Sayu: "If I gave up my dreams of growing tall, could I still fulfill everyone's hopes?" I've always avoided asking myself this question, it just makes me feel a little nervous... And I've yet to find an answer.
- Sayu: I still don't know what to do. *sigh* I don't even know what I actually can do... But, I thought that at least I can give you some fruit to eat, hehe.
- Sayu: You remind me of Sensei — you're kind and can even understand what Sensei was thinking.
- Sayu: So I thought I should at least show a little bit of enthusiasm.
You can call me "Sensei" if you like.
- Sayu: Huh? But wasn't I the one teaching you ninjutsu just now?
- Sayu: Although, I'm sure you know a lot more about life than me... So I guess you could still count as my teacher in that regard.
Why don't we just relax for now. We're supposed to be taking a break, remember?
- Sayu: Oh yeah, you're right. Hehe, I was getting a little carried away.
- Sayu: Why don't we go practice a little more ninjutsu after our break is up? Today is one of those rare days when I feel super motivated!
- Sayu: But never mind that for now, we've got lots of fruit to eat. C'mon, take whichever you like, hehe.

Trivia[]
- 変わり身 Kawarimi in the Japanese name is likely a reference to the fictional ninja technique Kawarimi no Jutsu (Japanese: 変わり身の術 "changed body technique") in which a ninja disguises and substitutes their body for an inanimate object.
