Suzu's powers are beyond the impossible. Neru's hair's ability to defy physics is also fairly impressive.
In somewhat related news, I took it upon myself to take part in Minami's fanart carnival armed with nothing but my barely-existent artistic talent and my MacBook's trackpad. I took the liberty of cross-posting the result (of questionable quality) to Danbooru; it can be found at post #537956.
