This is a lychee tea from MegMilk Snow Brand. Lychee is popular in Japan, so this is not surprising. The interesting/ugly comic on the package. I thought it might be a popular comic, but could not find any information about it anywhere. They mention that customers should look forward to the story, so I suppose there will be more in the series. Maybe this character appeals to kids, it certainly would not attract me to the product though. 雪印 ライチティー
