I'm not entirely sure specifically about a 'dog in Gintama sad radio story'. Gintama is known for its wacky and often emotional storylines. It could be that there's a story within the Gintama universe where a dog is involved in a sad event that was perhaps told on a radio - like a character reminiscing about a dog they lost or something similar.
I recommend the book "Possibly a Fake Silver Soul". It tells the story of Jiang Cheng, a transmigrator, who met the owner of Xinghai District and his girlfriend, Jiang Hua, who were traveling in the universe in the dragon vein of a certain planet. Later, he came to Earth and met his teacher, Yoshida Shoyo, who had influenced his life. He also met a group of friends. This included the transmigrator Okita Soki. This is a Silver Soul Doujinshi novel, don't miss it. I hope you like this fairy's recommendation. Muah ~😗
Gintama is purely fictional. It's filled with imaginative characters and scenarios that are not rooted in real-life events. The creators crafted a unique and entertaining fictional world for the audience.
Kagura was one of the main characters in Silver Soul. He was a very interesting and energetic character. The following are some of Kagura's classic sayings:
The world is full of opportunities, as long as you dare to think, you can do it.
There was no such thing as failure. It was just a temporary pause in success.
Living is not for others but for yourself.
In this world, only the living can see the truth of things.
What matters is not the result but the effort in the process.
If you feel pain, give up, because you have tried your best.
Everyone has potential energy, but it is easily covered by habits, blurred by time, and worn down by laziness.
The furthest distance in the world is not the distance between life and death, but the second I just got online, you went offline.
To defeat the enemy, you must first defeat yourself.
The biggest waste of time in the world is doing meaningless things.
