1) Shabekuri episodes with Aiba, Nino, and Ohno.
2) First episodes of Shiyagare
3) RAWS of C no Arashi, D no Arashi, G no Arashi, Mayonaka, Nama, Mago Mago, Arashi no Shukudaikun. BECAUSE THOSE SHOWS ARE EPIC AND THEREFORE SHOULD BE PRESERVED FOREVER
I'll update this post once I remember what I was looking for.
Thanks in advance.
