1. Hidan didn't die (probably because he couldn''t)
2. That's because there were upwards of 50 exploding tags, razor wire and a pit trap.
3. It's also because Hidan fell into shikamaru's trap, something Tezca wouldn't do.
4. Hidan was also immobilized first, which is something that couldn't happen to Tezca.
Tezca > Shikamaru
Tezca > Exploding tags
Tezca > Shikamaru + Exploding Tags
