@seisubtanabatafest day 4: longing, separation, reunion (late entry)

In the manga, the Rainbow Bridge meeting starts during sunset. I find it sad that the anime (and video game) doesn’t reflect that.

(This was originally made for the same (still WIP) MMV/AMV these edits were for: [link] [link] [link] [link])

(The “background” is from Tsubasa Chronicle anime.)

As long as your work follows at least one prompt for the day, you can submit it. Do I have to participate every day? No, that is not necessary. What if my work incorporates prompts from 2 different days? You can choose to post it on any of the 2 days, e.g. if you write a fic of characters being soulmates and stars, you can choose to post it on either day 1 or day 2. Can I submit a late entry? If you’re posting while the event is running (between 7 July and 13 July 2023), we are fine with that. However, if you can’t make that day, we will accept late entries. Keep in mind you will be posting outside the original posting period, but you can post whenever you can post afterwards. Are there any content restrictions? No, we do not believe in restricting problematic fictional content. As long as it’s properly tagged, we accept content of all ratings and themes. Are there minimum requirements for works? No. Do whatever you want as long as you create a work for the event. It can be any length or amount of effort you want to put in. What does "FREE DAY - choose your own prompt" mean on Day 3? You can choose a prompt that is not on our prompt list to use. This day has the most flexibility for the idea you want to create.
