  1. “Seiji is equal to a human around 18 years old in Elena’s world while Elena is equal to a human around 25 years old in Earth, right?” Not really. Average lifespan in Elena’s world is lower due to high infant mortality. If it’s anything like our world pre-industrial revolution, then humans should be able to live to 60s and higher if they make it out of adolescence. Even if we ignore that and accept the average lifespan to be 50, it is still strange to try and equate a 30 year old man with an 18 year old because they share the same life lived to average age of death ratio.

    I’m fine with the age gap, really. I just wish he didn’t act like a 15 year old harem protagonist. Why make him 30 if you aren’t going to use it for his character?

    • Adding on to this, Seiji should only equal to a human of 18 years of age in the other world providing that one year in Elena’s world is in fact longer than one in Seiji’s.

      Basic math:
      Seiji’s 25 years (assuming that its his 25th birthday) = (365 x 25 ) + 6 leap year days = 9131 days

      For Seiji to be 18 years of age in Elena’s world = 9131 days/18 years = 507.27 days per year.

      Basically, only if the years in Elena’s world consist of approximately 507 days + 1 day (on leap years), Seiji could be considered to be 18 years of age (amount of time he had been alive is equal).

      • Not. To. Mention.
        there is a large gap difference of basic intelligence between their world and the other.

  2. thanks for the chapter
    about the age problem
    the other world is based on the middle age
    at that time it was no problem for man in the 20th (form 20-30) to marries teenage girl
    as at that age the man has his one capital (money) farm or business and can feed family (when he was younger he was helping his family)
    as for girl if the family was that mean less mouth to feed and nobility (princesses included) they have political marriage so it not weird to married young

  3. As SightlierGravy mentioned, average age is low in pre-modern times mostly due to high infant mortality. Granted, they treated living to 60 / 70 much the same way we treat living to 80 / 90.

    I think the issue of their ages is a modern blind spot. How many of us would be surprised, I wonder, to learn that – statistically speaking – it is very likely that one of our pairs of great grandparents or great-great grandparents were of similar ages when they married? The modern issue (both of the age gap and especially of Elena’s age) are just that – modern constructions.

    Prior to the mid-twentieth century teenagers were not (in the west) considered old children, they were considered to be young adults, and once a female had a regular period she was considered to have reached the minimum age for marriage (although such was more the traditional approach rather than codified in law, which generally set it around 15 or 16 due to most girls have reached that point by then).

    The age gap is also less of an issue in the modern east. In China, Korea, and Japan (and probably other countries I have not looked into), although most marriages have far less of a gap, age gaps of 10 to 15 years are not unknown and in some places are treated much the same way an age gaps half that long – of 5 to 7 years – would be treated in Europe or America. There may be the occasional comment, but little else.

    Ultimately I guess it is a failure of the education system to teach history / historical perspective (“the past is a foreign country, they do things differently there”) and the modern tendency to treat even those in their early twenties as if still children. Note that in Japan at least, a teen who has finished middle school can get a full time job (although I think it requires parent / guardian permission).

  4. so are you saying that if the people on another world has only 20 years old lifespan
    then even 35 years old in earth can marry a 10 years old of another world?
    I can’t accept that logic
    i think its all about the difference of biological maturity of the person

  5. Lets be fair, this is a Japanese web novel based on Japanese culture because the initial audience is Japanese. There is a cultural difference exist when translated and read by non-Japanese. We should not based our culture value to judge theirs.

  6. In some parts of our world, a girl who has her first period is considered an adult. In middle ages Europe most female royalties and nobles are already married at 15.
    Where she comes from, Elena is probably considered an adult. Considering she’s royalty, it won’t be strange that she would have been married off to an old duke if Seiji didn’t come along.

  7. Wouldn’t this 50 year refer to life expectancy? Our life expectancy has varied everywhere from 30 to 80 along history so this is really just playing with numbers. Who cares about age in the first place as long as both are ok with it?
