Mini connection event (Found on Japanese Twitter Account)

Basically, everyday you can connect on this site and you get a piece (jigsaw looking) part of an illustration, that progressively gets filled after each daily connection.

From what I understand you will also get a (most likely digital) certificat if you completed the 100 day challenge.

Warning to not be dissapointed later : On the site there is the mention of a prize, which will be delivered for 1 random person who completed the challege.

Except that this part only applies to those living in JAPAN and in JAPAN ONLY.

Have fun !
