One idea could be to make a DIY gacha pon charm or keychain using clay or resin materials. You could also purchase a gachapon machine or mini figures for her to collect or display in her room. Additionally, you could get her a book about gacha pon, or tickets to a local gachapon museum or exhibit. If she enjoys crafting, you could even get her a subscription to a DIY kit club focused on making gacha pon items.
Or you can get her/him a star map with an important date you share.
