Just asking, as it would be worth buying if it had that in it.

its an ending as far as i remember.

i am not too sure about it, try checking the tags and peeking through the spoilers for the content in the game on vndb.org

also, if you are going to buy this version then i would rather suggest you to wait for the dev a bit for them to finish this game's remake on steam, you should probably check the steam page at least once before you make up your mind.
