Giveaways

A continuing series has been keychains depicting Mobile Suit Gundam characters as chickens, based on a popular manga of the same concept. Other items given away include CM collection CD-ROMs, exclusive alternate manga cover sleeves and cardboard calendar cubes.

Removed mention of same-sex marriage in The Witch from Mercury
In the July 26, 2023, issue of Gundam Ace magazine an interview with Mobile Suit Gundam: The Witch from Mercury's voice cast included a quote from Kana Ichinose in which she referenced Suletta and Miorine's marriage. While the wedding itself was not depicted on-screen, the characters are shown wearing wedding rings in the final scene of the series, with Suletta's sister Eri referring to herself as Miorine's sister-in-law. Miorine was also directly referenced as Suletta's wife by the official English-language Gundam Twitter account on the day of the finale. Previously, this account also posted tweets either in support of the main characters' romantic relationship or with an implied condemnation of other fan 'ships' with the heroines.

Following the release of the magazine interview, the hashtag スレミオ結婚 (SuleMio Marriage) trended in Japan.

However, days later the digital version of the Gundam Ace interview was edited to remove the direct reference to marriage, causing an immediate backlash from fans who claimed the characters' status as a married couple was being deliberately censored.

On July 30 a statement was released by Kadokawa, publishers of Gundam Ace, in which they claimed the discrepancy was a "proofreading mistake" and that the marriage reference was based on "editorial speculation". An accompanying statement was released on the official Witch from Mercury website in which these claims were repeated, in addition to implying the events of the series are open to interpretation by viewers, leading to angry or confused responses from fans and general viewers who pointed out Suletta and Miorine’s marriage was objectively confirmed both in the anime's final scene and by the characters' voice actors in an audio commentary for the final episode, and as such no room for 'interpretation' exists.
