Lyrical Seasons is a comic published in Megami magazine, with only one page per issue i.e, one page per month. Highly comical and draw by the quite famous doujin artist Chanomi, it is however labeled as "なのはStrikerS PROJECT" and if not canon, it is at least totally official.
For the record, Chanomi also made a double page of the Movie 1st Tribute Comics : 
.
I finally took some time today to scan my own copies of Megami and thought it would be better to share it with everybody :
Some pages are missing unfortunately since I only have n°2/3/5/6/7/8/9/10/11/12/14/15/16/17/18/24 (1&2). I hope someone will be willing to scan its own copies someday ^^.
As for the translations, I think there is none as for now ｡･ﾟ･(ﾉД｀)･ﾟ･｡.
Edit : Thanks to motaku96 for the 8th page of Lyrical Seasons!
Thanks a lot Nina! I just saw your posts in a Nanoha thread on /u/.
May I ask you how you buy the magazine?
Oh, I see, I didn't know about that website. Thanks a lot for the info Nina, hopefully someone will scan Vivid and the Movie manga.
Oh right, I asked about this on AS once. But I forgot to check if I got any replies -_-;
(Turns out no one ever did answer me)
Luckily, it looks like the 1 issue that I have is one of the one's you don't have. Page 8. I should be able to use the scanner at the library. Might not get around to it till next week or the week after though.
Oh and haru, you can always buy the magazines at hobbysearch too.
As promised, here's page 8.
First time using a scanner. Took a few tries to get it straight.
Thanks motaku!
I know it's not easy to scan a page from a mag' or a doujin without damaging it too much. I usually rotates the page once I've scanned it (with Gimp)that way I don't have to worry when I scan it about getting it perfectly straight.
I'll add your page in the first post if you don't mind, so it's easier to find.
I usually order Megami + CompAce (+ other stuff) here, at the end of each month. I didn't do it this time (a first since last July) because I planed to save some money, but I begin to regret it since the raws for the Movie first manga and ViVid are nowhere to be found yet >.>...
