Occasionally, the author or publisher may offer promotional freebies or samples. You can follow the official social media accounts of the 'Sword Art Online' franchise or the publisher.

The 'gate thus the jsdf fought there' light novel may tell a story full of action and adventure. Given that the JSDF is involved in fighting, it might be set in a fictional world accessible through the 'gate'. There could be political, cultural, and technological aspects explored as the JSDF tries to survive and succeed in this combat - oriented situation. It may also touch on the characters' personal growth and development as they face the perils of war in this new and mysterious place.
There may or may not be highly popular 'gate thus jsdf fought light novels'. The 'Gate' franchise has a base of fans who might be interested in light novels that expand on the military action with the JSDF. But popularity can be subjective. Some light novels might gain a cult following among fans who really like the idea of the JSDF fighting in the 'Gate' universe. However, without more specific research, it's hard to name any that are definitively popular.
I'm not entirely sure without more context. It could potentially be about a person's act of refuting the ideas, events, or characters in the 'Beelzy' short story. Maybe the narrator has a different view on the story's themes, like its portrayal of good and evil or the supernatural elements.
Love and sacrifice are likely to be common themes. Since the title implies a rather dramatic end with a kiss, there could be a lot about the power of love that leads to this ultimate sacrifice.
Well, from the title, it seems that the story could center around a gate. Maybe it's a portal to another world or a special location. And the JSDF is fighting there. Mizari could be a key figure in this fight, like an antagonist or an ally. But without reading it, it's all just speculation.
Survival could also be a theme. The JSDF soldiers might find themselves in a hostile environment on the other side of the gate, having to fight for their lives and find resources to survive while also trying to complete their military objectives.
Yes. Many things in science fiction have already become reality. For example, submarines were first imagined in science fiction novels long before they were actually built. So, as these fictional ideas turn into real things, they can be seen as normal fiction in the sense that they are no longer just wild, unproven ideas.
I'm not sure of a specific one to recommend right off the bat. You could try searching on fanfiction websites like Archive of Our Own. They usually have a wide variety of fanfics including ones related to this theme.
