Although Ene is 19 while Shintaro is 18, but I think it’s good and I highly recommend Ene as the oldest "senior”(年上)
Jin / Shizen no Teki-p, Kagerou Project’s creator
Kadokawa Mook Interview (2013)
other interview parts:
1.1 / 1.2 / 1.3 / 1.4 / 2.1 / 2.2
IMPORTANT NOTES:
* Regarding the term “senior” ( 年上 ) / “toshiue”,
* I clarified with @ayara-resara when checking the translation that the term much likely generally means “older person” in general.
* Please understand Jin used to joke around a lot in older interviews in general (before his series became a huge hit - he’s also commented numerous times on how he didn’t expect it to become so) and he’s a lot more professional now (compared to back then, anyway) in recent interviews!
* that said, Jin outright specifies Ene is “19″ in this interview!
* she was INTENDED to be OLDER THAN SHINTARO !!!
* this would also be the case for Takane (chronologically) !!
* The Japanese school year BEGINS ON/AROUND APRIL 1ST-2ND
* and ENDS DURING THE NEXT YEAR’S LATE MARCH.
* Kagepro begins on AUGUST 15TH,
closer to THE START of that timeframe.
* IF TAKANE BEGINS THE SERIES CLOSER TO 19 OR
* i.e. she begins the series at 18
* i.e. which is the case when going by a real-world
Japanese school system re: the conflicting ages issue
* AND AGES TO 19 BEFORE OR ON AUGUST 14-15TH OCCURING
* THIS WOULD MAKE HARUKA
* with his chronological birthday being DECEMBER 24TH
* 18 at the start of the series (chronologically) PRE-AUGUST 15TH
* and closer to 16 when he initially died “two years ago” !!!
* Haruka’s father told him in the 2nd novel Haruka also had
“ (ABOUT) 6 years left to live ”
when Haruka was 10 years old.
* if you use the Japanese school system for Takane & Haruka in order to understand this timeline you HAVE
to use it for ALMOST ALL THE OTHER CHARACTERS AS WELL.
* ( includes Momo Kisaragi & the Mekakushi Trio )
* ( no, they are not exempt )
* THIS WOULD ALSO IMPLY
* ENE’S/TAKENE’S CHRONOLOGICAL BIRTHDAY
* COULD POSSIBLY BE ON
* APRIL 1ST - AUGUST 14TH/15TH !! ! !! !
* The Japanese school year BEGINS ON/AROUND APRIL 1ST-2ND
* and ENDS DURING THE NEXT YEAR’S LATE MARCH.
* Kagepro begins on AUGUST 14-15TH,
closer to the start of that timeframe.
* Shintaro’s age + birthday combo
(“a rotten 18-year-old boy”) + April 30th
means he ages to 18
NOT LONG AFTER THE JAPANESE SCHOOL YEAR BEGINS.
* Ayano died closer to 15 “two years ago”.
* Ayano would be 17 in the present timeline, aging to 18 on Nov. 22
post-series (and after Hibiya ages to 12 on Nov. 4th)
* Shintaro & Ayano are canonically 1 school year BEHIND
Takane & Haruka.
* Ayano is canonically 1 grade higher than the Trio,
who are all in the same grade (11th grade during main story).
* the Trio are all canonically 1 grade higher than MOMO (10th grade).
* Kano (May 10) ages from 16 to 17 before August 14th-15th.
* Kido (January 2nd) follows to 17 from 16 post-series.
* Seto (*March 28) is the youngest, his birthday occuring near the end of a Japanese school year.
* Momo (February 14) would age to 16 CHRONOLOGICALLY
before Seto ages to 17 POST-SERIES, remaining 15 during Aug. 15.
* if she does not then her “age” conflicts with Seto’s, Kido’s,
and nearly the entire casts’ ages / the ENTIRE TIMELINE.
