Nosebleed

I almost want to back it so I can make my cat crossdress as a maid.
Also tfw you realize a cat custome is a better reward than most of Dies Irae's kickstarter rewards.

I received some nice cozy socks and a flannel shirt. These are some legit "you're now old, deal with it" gifts. 
My head also hurts from drinking too much.

Lucy -The eternity she wished for-
Summary
In the near future, androids have become the way of the norm. Emotionless husks of metal have become a part of human society, much to the dismay of the boy. The robot he found at the dumpsite though, this one was different. It laughed, it cried, it smiled, it has dreams, just like a human… 

Lucy The eternity she wished for is a Visual Novel, about a boy and an android. You play as the boy, who faces decisions and moral dilemmas in this near-future world. This is a story that has touched many hearts and continues to have a strong impact on those who partake in this compelling journey.'

Ending Guideline / Suggested Route Order
There are only 2 main ends to the game (and one extra ending) and from all my testing, they all depend on the very last choice you make, so if you want to go blind into it, it's a fairly safe thing to do because the last choice is quite obvious.
The vast majority of the other choices in the game are mostly for unlocking CGs and specific scenes, some of which unlock achievements.
Since there's only one major path to take, I have designed my walkthrough so that you can unlock the most achievements with one single playthrough. I will mark all the choices that unlock an achievent with underlined text. If you wish to do your own thing, you'll have to replay the game later to get the remaining achievements.

This walkthrough was entirely written and tested by me.
Please link to this post if you want to use it on your website.

The PC version is the original version of the game (i.e the doujin version). It has the original art and the original voice actors, as well as an extra chapter that wasn't included in subsequent versions.
The 3DS version is essentially a port of the PSP version (of course slightly altered to fit the 3DS environment, but the content is the same)
As I've said in a previous thread: The PC version has all the original content, so its value stems primarily from that. But the PSP/3DS versions have much better graphics and voice acting, which frankly make the experience a lot more enjoyable, even if the story is missing one chapter.
So the question comes down to what you value more. If you plan on getting both anyway, I'd advice playing the PC version and then the PSP/3DS version, since if you do it the other way around you'll be struck with quite a feeling of downgrade. If you're only going to get one version though, I recommend the PSP/3DS version since the experience they provide is a lot more superior to the original game. Yes, it's missing one chapter that was later added to the PC version, but imho that's not enough to excuse buying one over the other. The original game can really only be recommended if you're super into the franchise and want to see how the earliest version of the game was like.

Plot Summary (Source: Hau~ Omochikaeri):
Shou and Ren arrived at a beautiful town full of colourful flowers. They met the three sisters Haru, Kotose and Yukina, who run the cafe “Famille”, and he starts working there in exchange for a bed to sleep in.
In the middle of the night, Shou follows Haru far away from the town to a hill covered with flowers as far as the eye could see. He watched as a little girl whom Haru was embracing turned into a flower under the large moonlit tree. She noticed his presence and smiled lonesomely while looking fondly at the beautiful flowers in full bloom.
“I have survived up till now in this world by doing this. But I still want to continue living… even if it’s in exchange for other people’s lives.”
Shou looked up at the petals which fluttered down and responded:
“No matter what this world forces upon you, no matter how many people won’t forgive you... I’ll still pray for this world to end.”

I debated for a while on whether or not I'd publicly announce this. In fact, I still have many doubts, but I decided to go for it instead of hestiating to keep the momentum I have going right now.
Yes, I decided to start another translation project, and for a game I only very recently got into. Could this be the biggest mistake of my life? Who knows, but I'm doing it anyway.
I hope you'll bear with me on yet another journey that will hopefully not crumble.

For some reason after seeing the meme of the girl named Ren in that game I knew something was cooking itself. Anyways, good luck with that shit. Hope you can find what you're looking for.

@Mr Poltroon I don't like Nagi no Asukara, which should be an indicator that you'll probably like it.

It's not, the guys are still working on it: https://trjr.wordpress.com/
 

Shakugan no Shana is an interesting series because it's one of the few that ever adapted the entire source material from start to finish. 
I watched it a long time ago and enjoyed its first 2 seasons, the 3rd being a bit of a hit and miss as it went on, but the ending was satisfying. 
Considering your tastes, you're likely to enjoy the sort of drama Shakugan no Shana aims for. It has romance as a somewhat central element but the world is vast and many things are happening alongside it. If you like the idea of fighting for the ones you love, you're likely to be into it. 
I do not know how you'll feel about season 3, however. I personally thought the way they pushed the setting and drama in it was pretty forced to say the least in comparison to previous seasons, but it wasn't all bad either.
