While the first chapter is mostly serious, the tail end has Touta telling Yukihime about how it's his dream to climb the "Tower" in the capital, complete with dramatic closeups and art that implies this ascent to be some sort of Series Goal. Yukihime's response?
Yukihime: You mean the Japanese Orbital Elevator? If you pay for it, you could ride immediately. It's very reasonably priced at 400,000 yen. Touta: That's expensive! And also not the dream!
Also in the first chapter, we have this gem from Yukihime:
Touta has his first Who Wants to Live Forever? moment, and it's triggered by several increasingly trivial realizations. The thing that finally sends him over the edge screaming about how immortality can suck it? When he learns that he'll never go bald.
Touta flubbing Louis Armstrong's "What a Wonderful World" because his voice is still too pitchy and underdeveloped. The reaction of Yukihime has her being blown away by the flub too! What makes it even better is that his first note is spot on, making everyone think that he's a great singer until he actually launches into the song. Then it turns out that the reason why growing up is so necessary for the big dream is because part of it involves singing back-up at the Solar Olympics, and he wants to sing the way Louis Armstrong does.
Touta's rather mundane dream which involves growing old and drinking in a bar Rat Pack Style. Then Yukihimes reaction to said dream.
Yukihime: I get it, after two years I finally get it... you're an idiot.
When Kuroumaru is unconscious, Touta tries to pull down his pants to see if he's really a boy.
The reveal that Touta actually forced Kuromaru to sign a "friendship contract", just to be sure about the whole "defeat means friendship" thing.
Touta's Hot Spring Theory:
Touta: When two or more men are at a hot spring, they're obligated to try to peek at the girl's bath! But with Yukihime in there, we'll be flirting with death!
The result of the above? Yukihime bursts in to their side of the bath and tells them in Large Ham fashion that if they can steal her towel, she'll let them peep on her. Then she busts out one of her ancient spells...
Touta manages to get the towel off, and just before Eva agrees to show them, he goes, "I'm not interested in old Granny's body." Needless to say, Eva didn't take it well.
Kuroumaru tells Touta to be careful about trusting Jinbei, and that Touta is the gullible sort of person who falls for money scams. Once they find out how old Jinbei is though, Kuroumaru is overcome with emotion and starts hero-worshiping him.
Touta: If I'm the type that falls for scams, you're the type that gets dragged into weird cults, huh?
Jinbei takes Touta and Kuromaru to a Sword In The Stone that nobody has proven able to pull out. Naturally, Touta is able to do it easily... Because he was apparently the only one to notice the sword had a switch that could set it from "Super Heavy" to "Super Light".
Touta vs. Kuromaru in an arm-wrestling match... and all the orphans in the crowd cheering for Touta to lose.
Turns out the wrestling was for kitchen duty, and Touta is a really good cook. So when Touta loses, everyone wins (except him).
Touta Trains in Instant movement buying eating his meals and playing cats cradle only using his feet, and one of the orphans tries doing the same thing as he does.
Karin's text message to Touta:
Touta: Everyone's fine here. Where are you?
Karin: The Moon
Touta: The Moon?! Seriously?!
Evangeline shows up in her ten-year-old form, confusing Touta. Then she transforms back into her considerably more buxom Yukihime form... prompting Touta to complain about how she looks like a pervert without her pants.
Evangeline: What is it, you troublesome boy? Make it clear: do you prefer boing or no boing?
The four members of the group that captured Fate get one question each to ask. Karin asks who loved Negi more him or Yukihime.
The kicker? She says this just as seriously as the others when they ask their questions. She even claims it's the most important question!
While the serial killer is tracking UQ Holder, he realizes that Touta is about to break into his hideout. Turns out that they're now room mates.
Touta interrupts the serial killer before he does more than knock out a group of magic-wielding thugs. Then Ikku asks what they should do with the thugs.
Touta: Kick 'em!
Touta: I mean... call the police! And an ambulance for the old man!
Touta and Santa start bonding over Video games only a page after Santa tries to get Touta and Kuromaru out of his room. Apparently, Santa makes his living off of Let's Plays and video game tutorials.
