I'm not entirely sure if 'Uchuu Kaizoku Sara' is available as a PC visual novel. There are a large number of visual novels out there, and new ones are constantly being developed. If it's a relatively unknown or indie title, it might be harder to find. You could try searching for it on gaming forums or communities where fans of visual novels might have more information.
Well, 'Densha Otoko' isn't real. It's more like a made-up tale that captured people's imaginations. The characters and events were crafted for entertainment.
Di Renjie was a TV drama, and Naru was a character in the drama. Na Lu was the princess of the Yue Kingdom, beautiful and infatuated. She lived in hatred all year round, but she also loved her lover, Yaka. In the end, she was killed by the Fake Loyalty Festival (Sar Khan) for killing the king's envoy and the two princes, Vita and Jongta. Before she died, she cut open her face and reminded Di Renjie and the others that the ruling loyalty beside Di Gong and the others was actually Shaer Han in disguise. The role of Na Lu was played by Li Xi 'er.

Well, 'ao oni' could potentially be a character or a concept within the novel. Maybe it tells a story of this ao oni's adventures, its relationships with other characters in the fictional world. It could also explore themes related to good and evil if the oni represents the 'evil' side, or it might be a more complex story where the ao oni has a different nature than what is traditionally expected of an oni.
Nalu was a character in the TV series "Divine Judgment of Di Renjie", played by Li Xi 'er. She was the Yue Kingdom's Princess Consort, beautiful and infatuated.

The 'densha otoko real story' is about a man's experiences on the train. It might involve his daily commute, the people he meets on the train, and the events that occur during his train rides.
One common theme could be identity. Naruto having to come to terms with being an oni while still being a ninja. Another might be power struggles, as his oni powers could be either a great asset or a dangerous liability.
Since I don't have detailed information about 'oni chichi light novel', it might be a story that combines elements of Japanese supernatural beings (the oni) and a character named Chichi. It could be an adventure where Chichi has to deal with oni - related problems, or it could be a more character - driven story exploring the nature of oni and how Chichi interacts with them. Maybe it also delves into the cultural aspects of oni in Japanese culture.
I'm not entirely sure specifically as there could be different stories within 'ao oni light novel'. Generally, it might involve some unique characters, a fictional world, and a plot full of mystery or adventure.
