Tonikaku Kawaii

Fly Me to the Moon (Japanese: トニカクカワイイ, Hepburn: Tonikaku Kawaii, lit. "Adorable Anyways" or "Cute, No Matter What"), also known outside Japan as Tonikawa: Over the Moon for You, is a Japanese manga series written and illustrated by Kenjiro Hata. It has been serialized in Shogakukan's Weekly Shōnen Sunday since February 2018. The story surrounds the teen genius Nasa Yuzaki and his developing relationship with his new wife, Tsukasa, who saves him in a car accident at the beginning of the story.

Plot
Nasa Yuzaki is determined to leave his name in the history books. Ranking first in the national mock exam and aiming for a distinguished high school, he is certain that he has his whole life mapped out. However, fate is a fickle mistress. On his way home one snowy evening, Nasa's eyes fall upon a peerless beauty across the street. Bewitched, Nasa tries to approach her—only to get blindsided by an oncoming truck.

Thankfully, his life is spared due to the girl's swift action. Bleeding by the side of an ambulance, he watches as the girl walks away under the moonlight—reminiscent of Princess Kaguya leaving for the moon. Refusing to let this chance meeting end, he forces his crippled body to chase after her and asks her out. Surprised by his foolhardiness and pure resolve, the girl accepts his confession under a single condition: they can only be together if he marries her!

Why It Rocks

 * 1) Most romance animes take a handful number of episodes developing characters' relationships, then Tonikaku Kawaii took only the first few minutes of the first episode, leading the two main characters to get married on the day they first met, and believe it or not, it actually worked!
 * 2) * It uses the idea of an isekai (letting a truck run over a protagonist), but it instead got the two main leads to know each other.
 * 3) The animation is smooth, and it feels nice.
 * 4) Vibrant colors and simple but fascinating art style that matches to the show's tone.
 * 5) While the characters aren't too complex, but it doesn't stop them from being likable:
 * 6) * Tsukasa is a great female lead, very beautiful, very cool headed, a helpful housewife to Nasa, and very geeky towards many different kinds of pop culture (mh:greatestmovies:Star Wars, Marvel, and The Terminator).
 * 7) * Nasa is an interesting protagonist. Unlike any other, he's an honor student from his school, isn't afraid to ask Tsukasa to be his girlfriend when he first met her, kisses her whenever he wants to, sleep together, or hold hands.
 * 8) * Kaname, despite her age, she's very mature, gives Nasa advices on how to keep a marriage alive, and likes sex humour.
 * 9) * Aya, becomes Tsukasa's rival after finding out that she's married to Nasa.
 * 10) The opening Koi no Uta is memorable, and even Tsukasa's voice actress Akari Kito herself sang it!
 * 11) With the similar basis that is to How I Met Your Mother, it had really great life lessons/morals, like you don't don't get married because you've proven that you're in love, you get married to prove it, or knowing that a human being lives are short, but what's more important is that love is eternal.
 * 12) Fun and enjoyable storylines between Tsukasa and Nasa being a married couple, which is very uncommon for most slice of life animes or mangas out there.

Bad Qualities

 * 1) While the story is supposed to be a comedy and isn't meant to be taken seriously, the prologue offers a rather dangerous message of letting your priorities go first before safety. If it weren't for Tsukasa, Nasa would have died, and the story would have ended way before it began.
 * 2) Chitose, while a likable side character, can be very annoying at times. She's persistent and mostly getting in the way of Tsukasa and Nasa's marriage for the heck of it.
 * 3) Tsukasa's mention of the mh:greatestmovies:Marvel Cinematic Universe (from mh:greatestmovies:Iron Man to mh:greatestmovies:Avengers: Endgame) is cut from the anime, despite both Star Wars and The Terminator getting shout-out.

Trivia

 * The manga had many guest cameos; the platelet and red blood cell from Cells At Work!, Rikka and Yūta from Love, Chuunibiyou, and Other Delusions!, Yuu and Touko from Bloom Into You, or Korosensei from Assassination Classroom.
