I didn't go into this VN expecting much.  Judging by the cover (considering I am a bibliophile, you would think I would know better, lol) and the Getchu page, I thought it was going to be a half-nukige along the same lines as the Ren'ai Jijou series (since Otaku was written by the same guy).  However, I was surprised at what I got... the first addition to my 'Chicken Soup for the Soul' list since Natsuiro Recipe in mid-2015.

As a reference point, I almost never add VNs to the Chicken Soup for the Soul list.  The requirements for it are just too strict (low stress, soothing, mildly cathartic, and overall something that leaves you feeling better about the world afterward).  So, I generally expect years to go by between each addition to that list.  I specifically select these VNs for their restful properties, so the ones on the list are the kind of VN you should consider going to when you feel the need to just take a total rest from the stress of your life.

Now, this VN is a kinetic novel, which means there is only one ending and one story.  In fact, there are no choices in this game.  This isn't a bad thing, from the perspective of a game I'm adding to the list above.  To be blunt, choices are a type of stress-factor at times, so it is nice to just be able to read the VN without thinking about choices or looking at a walkthrough.  

The story focuses on a young scientist named Kyouji (he's in his mid-twenties), who, at the beginning of the story, has just finished his second and third prototype androids.  The important thing about these androids is that they have emotions and the ability to learn and think for themselves (in other words, human emulation and autonomous AI decision making).  This story is about how the three androids and Kyouji grow together, and it is mostly a gentle story about the family they form together.

The oldest android, Nect, is an 'older-sister' type who serves as Kyouji's accountant, assistant, go-between, and secretary.  She is good at keeping him from breaking the household finances and keeping him on track to finish whatever work he has taken on at any given time, but she is also very caring and protective about Kyouji and her 'little sisters'.

Lux is the second android, designed to be a reliable partner and possess a desire to help others.  This quickly turns her into what Kyouji refers to as a ダメ人間製造機 (a woman who reduces men to helplessness through her eager 'help').  She loves nothing more than to do things for others, including her sisters and Kyouji, and she feels the most fulfilled when she is doing her level best to spoil someone rotten.

Sphere is the third android, designed specifically to be like a younger family member.  She hates being lonely and wants the affection of her family members, and she also has the most effective learning ability, eagerly absorbing information about human relations from movies, anime, manga, and books. 

Overall, most of the VN is gentle, heartwarming slice of life, with frequent bits mild comedy (mostly running jokes like Roppu's desire to be modified by Kyouji) and occasional h-scenes (yes, they are occasional).  I honestly haven't felt this relaxed coming out of a VN in a while, and I liked the ending fairly well.  I give this VN high ratings for essentially erasing my stress from the work of the last few days, lol.
