Can you guys help me identify who the second girl in this video is?

This is a new idol group I discovered recently through one of their members (Nanaka Tomita). But I saw this TikTok a couple days ago and the second girl in the video caught my eye and I haven't been able to figure out her name. Can you guys help me or direct me to the correct subreddit for help, please? 🙏
