They announced the tokuten (extra merchandise when buying a game) for Irotoridori World’s End which is just a bundle pack including both the original game AND the fandisc and comes with ONE original light novel called Irotoridori no Mirai. They’re selling it for 10,290 yen. The light novel is always included but the tapestries are different depending on which shop you buy from. That’s how it works.

There was a recent update from Tokidan who is working on the translation for Irotoridori no Sekai (84.86% translated), they’re in the middle of edits to the translated script especially because of v1.1 changes. If you want to pick the game up, this is THE most excellent way to get it because of the extra goodies and because preorder count is how the industry makes its money. You need to use a mail proxy. Just email the link to http://yokattaweb.jp.
it’s not 85% progress it’s just 85% translated. editing is lagging far behind
Soon ~3~
Damn you…. I had to order this. Was just too good deal and this is my first “real” eroge purchase from Japan. Anyway thanks for tip Aaeru.
o/ awesome
I’m really late, but are there any sites that still have this in stock? I’ve looked at a few sites including what’s listed above, but it seems to be sold out everywhere.
yea you are a bit late. pretty sure getchu.com will have stock and amazon.co.jp
they may have run out on the tokuten though (if they even had any). have to email them to find out
Is this project dead or what happened to it?
is the irotoridori no sekai worlds end complete still available?
