On Sunday, January 18th, "Say You To Yo Asobi Sunday [Yu Serizawa × Maria Naganawa] #29" was broadcast on ABEMA's "Anime LIVE Channel."

In this broadcast, in honor of the first Sunday regular broadcast of the year, they conducted various segments including trying their luck. The fate of the promise that Serizawa and Naganawa made with viewers to "not change their weight even after the year-end and New Year holidays" was also revealed, making it an exciting Yo Asobi episode right from the start of the year.

■Serizawa: "My Body Has Muscle Memory!" What About Her Weight After the Temptation-Filled Year-End and New Year Holidays...?

This broadcast was the first Sunday regular broadcast of 2026, starting with the segment "Year-End and New Year Promise with Everyone... Results Announcement." They conducted a real measurement to see whether they achieved the promise made with viewers at the end of last year to "not change their weight."

When asked about her eating habits during the year-end and New Year holidays, Naganawa said, "I worked hard this year, so I couldn't hold back... I ate a ton during the New Year," but she expressed her determination, saying she had adjusted before the recording to fulfill the promise. Serizawa was also impressed, saying "Amazing...!"

On the other hand, Serizawa confidently declared, "I ate during both year-end and New Year!" She revealed her complex feelings, saying, "Dieting when you live alone is easy, right? But when everyone gathers together and it's like 'Alright, let's eat~!' I can't say 'I'm sorry, I'm on a diet...'"

With a staff member appearing as the measurer to conduct the proceedings, the measurement began in a serious atmosphere. After taking off even her sweater costume, thinking "This might be a bit heavy...", she successfully completed the challenge. She proudly declared her trust in her body, saying "I don't think I worked as hard as everyone thought. But I've never changed my costume size since my debut, so my body has muscle memory!" Viewers sent comments like "What a pro!" and "Her body remembers!!"

Naganawa also achieved the goal, giving a thumbs up to the camera saying, "I've been living with this day in mind since January 1st. I'm glad." Having successfully kept their promise, the two discovered they both have the same body shape concerns and got excited discussing body-building topics while munching on chicken as a reward for completing the challenge.
