Transmigrating with My Two-Dimensional Dream Guy

After a mysterious prophecy sends Lin Lin into the anime world, she unexpectedly gets a Summoning System! Lin: Who else would I summon if not my new husband, 5t5? Unfortunately, the System is defective. It can only summon characters based on keywords in Lin's mind, and its accuracy is terrifyingly low. Lin, unlucky at gacha, Wayne: "..." Help!!! Ding! The System has detected the keyword "white-haired guy who loves sweets"! Lin's eyes light up: Could it be... Then a disheveled middle-aged man with curly white hair drops out. Ding! "Confident, skilled white-haired teacher." Lin ponders: This one should be... Then a masked ninja drops out. Ding! "A man who will never go out of character." Lin despairs: Surely this time... A man wrapped in bandages drops out. Ding! "mdjdhd Host's favorite man..." Lin comes back to life: Ha, persistence pays off. At last, a certain scheming student council president holding a tennis racket drops out. Lin: Wait, isn't this my childhood crush?! After getting the wrong character four times in a row, Lin grumbles furiously: She knew it! And so, a dependable, responsible samurai dad, a gentle, confident ninja mom (check), an unreliable bandage-wrapped eldest son (check), a shut-in eldest daughter who can't live without making sarcastic remarks and has a strange cheat ability (question mark), and a powerful, scheming youngest son (check) finally set off on a cheerful anime quick-transmigration journey... Or not!!! -- Because of certain prophecies, Lin Lin is forced to travel to the 2D world. Luckily, she has teammates. Unfortunately, her teammates don't seem very reliable. A white-haired uncle who can't live without sweets, a disheveled teacher who loves reading Make-Out Paradise, a bandage-wrapped guy obsessed with drowning himself, and a scheming beauty who plays tennis in another dimension. Their leader, Lin Lin (choking back tears): Could everyone please help us out and come to our rescue? They may call themselves unreliable, but these people turn plenty of worlds upside down... The curses see the white-haired man's power for the Nth time; a certain technical college tries to start a tennis class; the rotten oranges experience for the first time the terror of being controlled by a master of plot twists... A useless detective discovers there are two people in the world who share his, uh, kindred spirit; the young Reaper's childhood friend might get swept away by tennis; an unnamed spy organization discovers that a genuine villain has infiltrated its ranks... Then there's the legendary teacher of the heir to a seafood company, and how the unspeakable Yokohama figure turns out to have so many close friends... Lin Lin, who seems to have no presence at all in this story: What teammates? Do I know them? A certain white-haired uncle: What teammates? Aren't I the pillar of this family? Then he begs his eldest daughter to buy him strawberry pudding. A certain white-haired ninja: What teammates? Aren't I the mother of three kids? Then he tries to get his eldest daughter to return the confiscated Make-Out Paradise. A certain bandage-wrapped guy: What teammates? Aren't I an eldest brother with a great responsibility? Then he happily takes out a rope to hang himself. A certain child of the gods: Ah, I'm just a sickly youngest son who knows nothing. Then he uses tennis to create a black hole. Lin (giving up): That's right, we're a loving family! Tips: 1. No romance, cheerful banter, and a challenge-based plot. 2. Most of the worlds featured in the story are from other works. 3. The Gintama vibe is strong. With such a different tone, someone's bound to drag them all off course (lights cigarette). 4. No romance, but feel free to imagine whatever pairings you like. Theme: Friends are a precious treasure.
