A Tribute to Yuko Shimizu – Kawaii Meets the Universal Century
1 November 2026
1 November 2026 marks the 80th birthday of Yuko Shimizu, the original designer of Hello Kitty.
First introduced in 1974, Hello Kitty has grown into one of Sanrio’s most recognisable characters, capturing the hearts of generations through her simple yet enduring design.
To commemorate this occasion, this build brings together two familiar icons from very different worlds: Sanrio’s beloved Hello Kitty and Bandai’s iconic RX-78-2 Gundam.
Here’s a look at the painting, detailing and assembly process.
1. Base Coating and Colour Treatment
All parts were initially airbrushed while still attached to their respective runners, using GSI Creos Mr. Hobby Mr. Color No. 13 Neutral Grey as the base coat.
The original moulded colours were subsequently treated as follows:
- Grey parts: Retained in Mr. Color No. 13 Neutral Grey.
- Red parts: Airbrushed with Gundam Color UG10 MS Char’s Pink for a weathered finish.
- Yellow parts: Airbrushed with Mr. Color No. 109 Character Yellow.
- Blue parts: Initially airbrushed with Gundam Color UG02 MS Blue. The weathering outcome was not satisfactory, so the parts were subsequently oversprayed with Mr. Color No. 323 Light Blue.
- White parts: Following the Neutral Grey base coat, airbrushed with Mr. Color No. 107 Character White.
The blue parts required a change of direction, with Light Blue replacing the initial MS Blue treatment to achieve the intended appearance.
2. Panel Line Accent and Detailing
Tamiya Panel Line Accent was applied selectively according to the individual colour groups:
- Neutral Grey parts: Pink-Brown.
- White parts: Pink-Brown.
- Blue parts: Pink-Brown.
- Yellow parts: Minimal application.
- Red parts: Black.
Gundam Helmet – Special Detailing
The Gundam helmet, specially designed to fit Hello Kitty’s head profile, received additional attention.
While Pink-Brown was used for the general panel lining on the white parts, it did not quite convey the mechanical appearance intended for the ventilation details on the helmet’s side cheeks.
For these specific areas, Tamiya Panel Line Accent Black was used on the side-cheek vents, as well as the three stripes of fur on both cheeks.
This provides a more pronounced mechanical appearance to the helmet while retaining the softer Pink-Brown treatment elsewhere.
Cleaning Up
After application of the panel line accent fluids, excess residue was removed using cotton buds dipped in Tamiya X-20 Enamel Thinner.
3. Assembly
Assembly was relatively straightforward, with no major complications encountered.
The individually painted and detailed components were brought together to complete the SD EX-Standard Hello Kitty / RX-78-2 Gundam.
The interchangeable components also provide flexibility in how the completed kit can be displayed.
4. Display Configurations

Configuration I – RX-78-2 Gundam and Hello Kitty
The RX-78-2 Gundam retains its original configuration, standing alongside Hello Kitty in her familiar appearance, wearing a customised Gundam helmet.
The oversized helmet is specially designed to accommodate Hello Kitty’s head profile.
This arrangement allows both characters to retain their individual identities while sharing a common Gundam-inspired aesthetic.

Configuration II – Hello Kitty-Headed RX-78-2 Gundam
Alternatively, Hello Kitty’s head, complete with her Gundam helmet, can be mounted onto the RX-78-2 body.
The kit provides a dedicated neck adaptor to facilitate this arrangement. A separate backpack component is also supplied to accommodate the oversized Hello Kitty Gundam helmet, which is considerably larger than the standard RX-78-2 head unit.
The result is an interesting hybrid, combining the familiar mechanical proportions of the RX-78-2 with Hello Kitty’s unmistakable character identity.
An Alternative Head Swap
The interchangeable components technically allow the opposite arrangement, with the RX-78-2 head mounted onto Hello Kitty’s body.
However, this particular combination does not quite work visually for me, and will therefore be excluded from this review.
5. Final Thoughts
The SD EX-Standard Hello Kitty / RX-78-2 Gundam offers an enjoyable crossover between Sanrio and the Universal Century.
Both the original RX-78-2 standing alongside Hello Kitty in her customised Gundam helmet, and the Hello Kitty-headed RX-78-2, make interesting display options.
A little meeting between kawaii culture and the Universal Century.
Happy 80th Birthday, Yuko Shimizu!
Thank you for creating a character whose simple yet enduring design continues to bring joy across generations.
