A complete look at one of the earliest and most iconic pieces of SPC/KNT music media — the debut single by Reina Yazawa (谷沢伶奈), released March 5th, 1990.

This single contains:

① おっとどっこい日本晴れ (Ottodokkoi Nihonbare) — Opening Theme

② To Be Yourself — Coupling Track

• Both songs appear again as karaoke versions on some formats.

📼 Cassette (KISA 2)

Label: Starchild– KISA 2

Format: Cassette, Single, Stereo

Released: Mar 5, 1990

The original 1990 tape release under King Records’ Star Child label.

Features bright, colorful KNT artwork on the front jacket, paired with a very charming early-90s idol photo of Reina Yazawa on the reverse.

Tracklist includes both vocal and exclusive karaoke versions.

💿 CD Single

Label: Starchild – KIDA 2

Format: CD, Mini, Single, Stereo, 8cm

Released: Mar 5, 1990

The CD edition mirrors the cassette artwork but includes full printed lyrics, a singer profile, and promotional photography.

This version is often the easiest to find today and remains a beloved collectible thanks to its crisp print quality and bonus insert content.

📀 7” Vinyl (17DH-2034)

Label: Starchild – 17DH 2023

Format: Vinyl, 7", 45 RPM, Single, Promo, Stereo

Released: 1990

The rarest format — a promotional 45rpm vinyl release not sold commercially.

Plain red Star Child labels with white text, matching the era’s style.

Pressed for radio and industry use, making surviving copies surprisingly scarce in the wild.

📝 Why This Single Matters

This release marks:

• The first official physical media tied to Kyatto Ninden Teyandee

• The debut of Reina Yazawa as a singer

• The beginning of KNT’s long (and chaotic) merchandising history

• A fascinating snapshot of 1990s anime + idol culture crossover

It’s one of the foundational pieces for any serious KNT/SPC archivist — a perfect blend of character art, idol marketing, and early anime music production.
