Shadowslayer is indeed available in Chapter 3-5. Try to check the Legendary Booster Pack, you'll find all the available Legendary items listed there, including Shadowslayer. You can get Shadowslayer from Boosters, Chests, Season Packs, and random drops from fights. Keep in mind that the chance is very low though, unless it's a Booster or Chest of Legendary tier.

The weapon that will be replaced by that Naginata (Improved Pruner) is not Shadowslayer, but Fate's End, the Legendary Iaido Katana. Which will happen in Chapter 4. Shadowslayer itself is available up before Chapter 6, in which it will be replaced with the Legendary Sai. So, you still have lots of times to acquire it. Replaced items are still obtainable though, but only through Archive Packs.
