Mokumokuren (Original Story)

Chiaki Kobayashi (Voice of Yoshiki Tsujinaka)

"Congratulations on the announcement of Season 2 of The Summer Hikaru Died!

It's not an exaggeration to say that the summer of 2025 was defined by this series for me. It was such a meaningful time, and I'm truly happy to see the story continue- and to once again portray Yoshiki Tsujinaka.

Even with all of Yoshiki's struggles and hardships, I'm eager to see where his journey goes next.

I hope you'll stay with us, and thank you as always for your support!"

Shuichiro Umeda (Voice of Hikaru)

"Congratulations on The Summer Hikaru Died getting a second season!

I'm truly happy. I can't wait to spend more time with Hikaru and the others when we return to the recording booth.

I'm also really looking forward to sharing this second season of the anime with all the fans.

Thank you so much, as always, for your support!"

Introduction

In a certain village
Since their childhood, they have grown up together.
Yoshiki and Hikaru, childhood
friends.
the sun shining down on them
the chirping sound of a cryptotympana facialis
Ice cream on the way home

Laughing over trivial things
One day in summer, no different from any other day

...... You're not Hikaru after all, are you?

Half a year ago, Hikaru went missing in the mountains.
A week later, he came back on a whim.
The voice, the figure, the thing that looked like Hikaru
What was stirring inside...

"Hikaru is no longer with us. ...... if that's the case."

Starting the days with "something" in the form of a friend,
The "same as usual" everyday life.
But at the same time...
Strange incidents begin to plague the village.

Falling into the unknown "something"
The curtain rises on a coming-of-age horror story.
