Heiji, Kazuha, and the Naniwa Harukas Confession

Heiji's Confession Finally Succeeds

“Akane-iro no Senshuraku” brings Heiji to Osaka with one personal objective: finding the right moment to tell Kazuha how he feels against the sunset view from Naniwa Harukas.

A murder case interrupts that plan once again, but the final episode eventually gives the pair the moment that had repeatedly eluded them. Yuko Miyamura also celebrated the development, describing Heiji's confession as successful and the pair's feelings as finally mutual.

Gosho Aoyama Wrote New Dialogue After the Confession

The story does not stop when the episode ends. Yomiuri TV has prepared a “Heiji♡Kazuha Special Voice” written specifically by Gosho Aoyama.

The audio depicts their conversation while leaving the observation deck. It does not appear in the manga or TV episode and is played exclusively in the Harukas 300 elevator descending to the 16th floor.

The Confession Location Can Be Visited at Harukas 300

Harukas 300 has also recreated the spot corresponding to the Naniwa Harukas scene.

Footprint markers show where Heiji and Kazuha stood, while visitors can hear audio from the anime scene and look out over Osaka from roughly 300 meters above ground, directly connecting the fictional location with its real-world model.

Volume 109 Already Teases Their Next Development

“Akane-iro no Senshuraku” originates from Volume 106, but Heiji and Kazuha's story continues beyond it.

Shogakukan has confirmed that Volume 109, launching October 16, 2026, returns to the pair after the Naniwa Harukas incident. Its official synopsis even notes that the two seem somewhat awkward after what happened there.

Why This Matters

1) One of Conan's longest-running romances finally moves forward

Heiji and Kazuha have clearly cared for one another for years, but his confession attempts repeatedly failed or were interrupted.

2) Gosho Aoyama added story material outside the manga and anime

The post-confession conversation was written specifically for the Harukas 300 experience.

3) A real location becomes part of the story experience

Abeno Harukas is not merely promotional scenery—it is the real-world counterpart to the place where Heiji finally speaks his feelings.
