House Wellness Foods Corporation launches a collaboration campaign between the TV Special Anime "The Quintessential Quintuplets*" and their beverages "MEGASHAKI" and "NERUNODA" from February 9 (Mon) to May 8 (Fri), 2026. Original illustrations have been created to match different moments: when you want to feel refreshed and during relaxing times. Exclusive original goods and limited wallpapers will be available through lottery prizes. Enjoy special moments with the quintuplets both during energetic "ON" daytime hours and relaxing "OFF" rest time.
"MEGASHAKI" is a refreshing beverage that helps clear drowsiness with spice stimulation and cooling sensation, supporting energetic efforts in various scenes such as work, study, driving, and hobbies. "NERUNODA" is a functional food containing GABA, a functional ingredient. GABA has been reported to help improve sleep quality (depth of sleep, refreshing awakening).
For this collaboration, original illustrations were created for both MEGASHAKI and NERUNODA.
The "MEGASHAKI" visual features a newly illustrated waiting scene where the five quintuplets are filled with smiles, energy, and joy when they meet. The original costumes incorporate "lightning bolts," the image icon representing MEGASHAKI's "refreshing feeling from spice stimulation and cooling sensation."
The "NERUNODA" visual shows the quintuplets spending relaxing time while reminiscing about the fun moments of the day. It features matching roomwear for all five quintuplets designed in NERUNODA's signature light blue color.
By purchasing eligible products and applying through the special website, customers can enter campaigns for original illustrated goods and other prizes. Additionally, a follow & repost campaign on the House Foods Group official X account offers chances to win original QUO Card Pay.
