The Grandparents
Tropes that apply to both
Old
Rejuvenated
The titular grandparents of the series.
- Chick Magnet: In his youth, Shouzou was a very handsome man with no shortage of women flocking to him, forcing Ine to scare them off. Even Shouzou's daughter-in-law and granddaughter are smitten by his looks after he regained his youth, along with his female elderly peers swooning.
- Dude Magnet: Like her husband, Ines has her own number of male admirers and suitors in her youth, with Kitamachi being one such example. After regaining her youth, plenty of her male elderly peers are greatly enchanted to the point where their blood pressure rises.
- Fountain of Youth: As a result of a strange dream about a giant hourglass, especially after eating a golden apple in the anime, both Shouzou and Ine regress from elderly to youthful adults. Though Shouzou later finds out that the hourglass is not infinite, meaning that they'll still die naturally in a couple of years.
- Good Parents: They're both kind and supportive parents to their sons, Yoshiaki and Takahiro. Even after their sons are grown up and become fathers of their own children, along with the Saitou couple regaining their youth, this doesn't stop the Shouzou and Ines from doting and looking out for them.
- Happily Married: They are greatly in love and held a stable and loving marriage up to their twilight years. What makes it more impressive is that they were ahead of their time compared to how marriages were usually conducted in Japan.
Shouzou Saitou
Shouzou Saitou
Voiced by: Shin-ichiro Miki
Shouzou wondered about his life with Ine, having been together for fifty years already. Given their busy life and general lack of excess finances, many things couldn't be done.
A sudden dream about an hourglass that was turned around led to him turning young again, albeit with his hair remaining as gray as ever.
- Abusive Parents: It's implied that he didn't along with his father much. The reason why he took up house chores with Ine is because his father was a very demanding person always ordering everyone around.
- Book Dumb: He never received a formal education due to his standing as the second son.
- Brought Down to Badass: While he temporarily reverted back to his elderly appearance, Shouzou still possesses some of his youthful vigor.
- Butter Face: While Shouzou gained his original bald, elderly appearance upon his age temporarily reverted back to normal, he still has his somewhat youthful muscular build.
- G-Rated Sex: Implied to leave to masturbate several times. He still frequently requires the bathroom at night because their bodies are 'young' again, and one time, he disappears to the toilet when he gets visibly aroused at the thought of a young-again Ine in a swimsuit.
- Insecure Love Interest: Shouzou has deep feelings of inferiority regarding his worth as a spouse to Ine due to his humble background and being unable to provide his wife with the luxuries she deserves.
- Mundane Luxury: Regaining a full set of teeth alongside his youth made him happy because he could chew all sorts of foods easily again.
- Mundane Made Awesome: Some of his actions get treated this way, like trimming the hedge with a chainsaw
◊. Usually when some teenagers complain about tedious tasks and decide that it's pretty cool, after all. - Shipper on Deck: Ready and willing to lend Shouta a hand in getting closer to his granddaughter Mino. He even took Ine out of the room and gave Shouta a thumbs up, so he'd have the chance to ask Mino to the bonfire dance.
- The Power of Lust: Pretty much mentioned in-universe as to be what gave him the strength to beat his oldest son in an arm-wrestling match because a win meant they'd get a room with an open-air bath for a trip to Atami.
- Unwanted Harem: Played for laughs, he gains quite a following of women — old friends and even his own granddaughters — who are clearly infatuated with his younger looks. Though everyone knows they can't get between him and his wife.
- Wacky Parent, Serious Child: Played with. Shouzou is the jovial and now youthful parent compared to his son, Yoshiaki, a middle-aged man with the expected stern demeanor.
Ine Saitou
Ine Saitou (née Sasaki)
Voiced by: Mamiko Noto
Ine was overall happy with her life and only hoped to continue to be able to spend time with Shouzou. A sudden dream about an hourglass that was turned around led to her turning young again, albeit with still-gray hair.
- Broken Bird: She was this in the past. Following a complicated family situation, Ine became emotionally distant and introverted.
- Cuteness Overload: When Ine loses her memory and meets Mino for the first time, she gushes over how cute her granddaughter is and hugs her.
- Dark and Troubled Past: While she initially had a very privileged life, being the daughter of wealthy parents and going to an all-girls school in Tokyo, that all changed on the day of The Great Tokyo Fire Raid, which left her homeless and an orphan. In desperation, she moved in with her mother's relatives, but due to her father's arrogance against his wife's rural and poorer in-laws, she was shunned and due to her Tokyo dialect, was ridiculed for it. She ended up a Broken Bird on the verge of a total mental breakdown until she met Shouzo.
- Delicate and Sickly: Ines tends to be ill at certain points in her sons' childhood. Then, when Takahiro was an adult studying for his medical exams, Ine developed liver cancer that slowed down due to taking medication. After her youth is restored, the liver cancer has regressed to the point of non-existent.
- Ear Cleaning: Shown to do this to several people. First to her granddaughter Mino, and Shouzou later, noting that it was a common thing when they were newlyweds. Even Shiori gets an ear-cleaning, albeit in secret.
- Easy Amnesia: She hits her head in Chapter 83, resulting in her reverting to her younger self, including regaining her black hair, and not remembering anything about Shouzou or her life with him.
- Mundane Luxury: She mentions being able to eat a full bowl of rice or having water coming out of the tap to be a luxury she took for granted when industrialization caused her family to lose its standing.
- Silk Hiding Steel: She's got quite a tough streak behind her laidback smile, showing that she never quite lost the toughness from her old rebellious youth.
- Uptown Girl: She came from a rich and influential family, way too out of Shouzou's league as the son of a farmer family.
