I found this info, it was just released in November last year. I hope someone can get the manga and translate it for us. I love this story and would love to know what happens as they get older.

Unfortunately if I'm not wrong vol.3 is this one, if you take a look at the chapters from 7 to 23 they're listed as volume 2 which is impossible, a volume usually has around 6 to 8 chapters (sometimes more depending on how long the chapters are) （/TДT)/
17 chap came out on October 30 and 3d vol on November 15
Maybe bc i got one volume and it does not say volume 2 or 3 idk
Theres 4 books is not the end http://www.cdjapan.co.jp/searches?term.media_format=&q=Hinekure+chaser
OKay so I saw on a BL fb page that volume 3 is set to come out but when I foudn some things online it looks like it's what they called volume 2 here. I'm confused on if this is the final one or not.
