Father: This is your baby sister, Kun.
Mother: Isn't she precious?
Kun: [gasping in amazement] She is.
[pokes his finger against her delicate hand]
Mother: You have to be gentle with her.
Kun: [gently takes hold of the baby's hand; she opens her eyes]
Father: She's awake. I think she's staring at you, Kun.
Mother: Come on, her eyes can't even focus yet.
Father: Well she sure looks like she's staring to me.
Mother: You must always be nice to her, okay?
Mother: And you have to protect her no matter what.
Mirai: You did it again. You tried to hit me with your bullet train even after Mom told you not to.
Kun: But it wasn't a bullet train!
Mirai: You aren't supposed to use a bullet train to hit people.
Kun: It was a Super Azusa.
Mirai: [angrily] I don't care what kind it was!
Mirai: And why can't you be a little nicer to Mom?
Kun: I don't know, I just can't.
Mirai: It's her one day off from work. She doesn't get many and she has to spend it fighting with you. Come on, try.
Kun: [sniffling] I know... I'm not cute.
Kun: [crying, wipes tear from his eye] Both Baby Mirai and Yukio are really cute. Not me. I know I'm not that cute anymore.
Mirai: Oh come on, that's not true. You're very cute!
Kun: [walking away]
Mirai: You're the cutest! Adorable!
Kun: [crying harder; runs away]
Kun (High Schooler): [off-screen] That's just awful. Yep, a complete wreck. I'm talking about your attitude. Boy, does it stink.
Kun: [looks inside train station, sees a high schooler sitting inside] Hello?
Kun (High Schooler): You're supposed to go camping, am I right? Catch bugs, watch fireworks, all that stuff. And you guys will be staying at your grandparents' place. It's the summer you've all been looking forward to. Think of all the happy memories you could be making together. But instead you don't wanna go. Why is that?
Kun: Uh... how do you know? Who are you?
Kun (High Schooler): What's more important, the color of your pants or your memories? Well, it's your choice. Just go home and say you're sorry already.
Kun: NO. I do NOT like them.
Kun (High Schooler): What?
Kun: [referring to his pants] AND I WILL NOT WEAR THEM!
Kun (High Schooler): [getting annoyed] No, you do not not like them.
Kun: [as a train appears] No, I don't not not like them!
Kun (High Schooler): No, you do not not not not like them!
Kun: Yes, I do NOT not not not like them!
Kun (High Schooler): NO! You do *not* not not not not not like them!
[train pulls into the station. Doors open]
Kun (High Schooler): Don't get on!
[looks back in hesitation]
Kun (High Schooler): Stop! Don't get on, 'kay?
[whistle blows. Kun glowers at high schooler and bounds for train]
Kun (High Schooler): No! Wait! Wait!
Kun: [glowers at boy as the train pulls away]
Kun (High Schooler): [gazing after it in disappointment] Little brat.
