Onigiri Hollow is a bonus dungeon in Shiren 5 with a unique dungeon collapsing mechanism. You can't take Draft:Shiren 5 2020:Items, Gitan, or allies into the dungeon, but you can request rescue up to 3 times and you do keep any items you have on hand if you win. The dungeon is daytime only. The goal floor is initially 20 F, but after first victory the goal floor becomes 99 F and stays there permanently.

Gaining Access

This is the most complicated dungeon to unlock, or at least the longest and grindiest. Basically, you need to complete Decchi's side quest. He's the secretive man with the blond spiky hair that sometimes appears in different places around the starting villages. If you regularly go around talking to all the characters between dungeon runs and doing what they hint you to do, you'll eventually unlock this dungeon and probably everything else that can be unlocked as well, but if you did that you'd end up talking a large number of characters over and over again even though they usually don't have anything new or unique to say. Here are the specific steps (taken from this external webpage):

• Talk to the lady in front of the Storage building in Nekomaneki Village. (Her name is just "Lady". She has blue and purple hair and walks a little bit rather than standing still.)
• Go into a dungeon and come back.
• Talk to the same lady again.
• Talk to Decchi in the NW area of Nekomaneki Village.
• Go into a dungeon and come back.
• Talk to Decchi in the SW area of Nekomaneki Village.
• Check all of the small cat statues in Nekomaneki Village. There are 6 in all: 2 in front of the Point Shop, 2 in front of the Dungeon Center, and 2 in front of Hotel Nekomaneki.
• Check the large cat statue above the exit to Inori Village for a Revival Herb.
• Go into a dungeon and come back.
• Talk to Decchi again in the SE area of Nekomaneki Village. You'll get an Undo Herb.
• Go into a dungeon and come back.
• Talk to the lady in front of the Storage building again.
• Go into a dungeon and come back.
• Talk to Decchi in the W area of Inori Village.
• Go into a dungeon and come back.
• Talk to Decchi in the E area of Inori Village.
• Check all the pots in Inori Village. There are 2 outside, 2 in the middle house, and all the other houses except the leftmost house have 1. That should be 7 in all.
• Check the well in Inori Village. You'll get a Kabura Katana.
• Go into a dungeon and come back.
• I think at this point you also need to talk to Decchi one more time, in the E part of Inori Village, where he says goodbye and disappears for good.
• You may also need to go into another dungeon and come back one more time.

Presumably, going into the dungeon means advancing the run counter, so doing things that don't advance the run counter probably won't work to advance this unlock. Needs confirmation. In any case, after completing all the above steps, the next time you enter Inori Village, you should now see a cutscene of a little girl losing her mom's special onigiri as it rolls into a hole in the rock wall in the NE part of Inori Village. As usual, Koppa offers up Shiren's help, and Shiren agrees. Shiren then punches the rock wall where the onigiri disappeared, opening up the entrance to Onigiri Hollow. You can now play Onigiri Hollow whenever you want from this location.

Incidentally, if you talk to the lady in front of the Storage room again, she now seems to have fixed text mentioning that Decchi Man has gone away in search of his happiness.

Unique Features

• You are given a partial map of every floor, showing all the rooms, passageways, and the staircase.
  • Unlike the full map like you get with a Navigation Scroll, the locations of monsters, characters, or items are not shown.
• After you enter a room then exit it, the room collapses, with every space turning into a wall.
  • Shops and the room with the staircase do not collapse.
  • This kills all monsters (and traps?) inside, but you don't receive exp for it.
    • Items, including monster drops, will be buried under the walls and can be dug out.
  • Standing in the doorway lets you see into the room, and monster can see you and move toward you, but it doesn't count as entering the room so leaving the doorway doesn't cause the room to collapse.
• As with most bonus dungeons, item distribution differs from baseline.
  • Items that let you escape from being trapped are much more common than usual.
    • These include Rusty Pickaxe, Boring Staff, Warp Grass, Blink Bracelet, and Black Hole Pot.
  • Other than the above, the item distribution seems in line with other dungeons where you cannot take items in, such as Primordial Chasm.
• The dungeon is daytime only.
• Talismans and Scrolls are pre-identified. (Confirm / Update)

Final Reward

When you descend past 20 F, you come to a dead end and meet the Mountain Lord. He asks if you've lost something, and gives you the choice of a Gold Onigiri, Silver Onigiri, or mom's special onigiri.

Gold Onigiri and Silver Onigiri are exceptionally rare items. Getting them as reward items from this dungeon may be the only way to get them at all (aside from trading with other players). Neither will rot, become grilled, or be destroyed by monsters or traps, and having them in your main inventory causes you to get more Large Onigiri (Gold) or regular Onigiri (Silver) from monster drops. You'll need both to complete the Item Book.

But don't be tempted by the greedy options, they are traps! If you choose the Gold Onigiri, all your equipment rusts but you get a consolation Plating Scroll. If you choose the Silver Onigiri, all your equipment becomes sealed but you get a consolation Exorcism Scroll. But if you choose mom's special onigiri, the Mountain Lord likes your honesty and you get all 3 items with no downside. (Gold Onigiri and Silver Onigiri are real items, but mom's special onigiri is not actually an item; it doesn't show up in your inventory, it just advances the plot. As usual, you get the chance to organize inventory and discard items if need be if you don't have enough room to hold the special reward items.) You then get a cutscene of returning mom's special onigiri to the little girl, making her very happy, and thereafter you no longer see her crying in front of the Onigiri Hollow entrance. After completing the dungeon for the first time, the dungeon's goal floor becomes 99 F and stays there permanently.

If you beat the 99 F version of the dungeon, the Mountain Lord gives you the choice of two boxes to choose from, one of which is empty and the other of which has either a Gold Onigiri or Silver Onigiri.

[Open question: if you choose either Gold Onigiri or Silver Onigiri the first time, does the goal floor advance to 99 F, and is there a different ending cutscene with the crying girl, or does it simply count as a failed run and the goal stays at 20 F?]

Farming Opportunities

This is the only place you can get Gold Onigiri and Silver Onigiri.

Both Escape Scrolls and Blank Scrolls appear in this dungeon, so it is possible to farm items out, but it is not particularly easy. Items you can find here include Grilling Pot, Black Hole Pot and Blink Bracelet.

Strategy

Beating the initial 20F version of this dungeon isn't terribly difficult. You should plan out your path through the rooms and passageways before you leave your first room, so you can maximize exploring the floor before leaving. If you don't have any way to deal with being trapped in a tunnel yet, make sure to end your path at the room with the staircase. You can safely explore any room adjacent to the room with the staircase, so long as you always exit back towards the room with the staircase. (Same goes with shops.) But soon enough you should get multiple Rusty Pickaxes and Boring Staves, which lets you explore almost any room you want. Just don't rely on the Rusty Pickaxe to be able to dig you out of trouble. Make sure you have a Boring Staff or Blink Bracelet before you try any dangerous routes. If you have the option of using either a Rusty Pickaxe or a Boring Staff and you need to dig through 5 walls or less, it's probably better to try the Rusty Pickaxe first to try to preserve Boring Staff charges.

Because the Blink Bracelet is so common, avoid testing an unknown bracelet that might be a Blink Bracelet until you're done searching the floor and the only room left is the room with the staircase. Then try on the unknown bracelet for a few turns and see if you teleport. This way, you won't accidentally teleport away from a room before you were ready, destroying items you wanted that were still on the floor.

Warp Grass can also let you do a dangerous search pattern, though you have to be careful how you use it. For example, you can explore all rooms in a chain that ends far away from the exit room, and still be certain you can get out (provided the Warp Grass is not sealed!). Just make sure to leave the room you're in by entering a hallway, forcing that room to collapse as well, so that there is only one room left standing—the exit room—and then eat the Warp Grass. (If you eat the Warp Grass before destroying the room you want to leave, you may warp into the same room.) Warping always places you inside a room, never in a passageway, so you want to make sure you can't possibly land in a room that has no route to the staircase. [TODO: confirm that you can't warp to land inside a maze either. Probably not, since a maze is shown as a hallway in the map and doesn't collapse after leaving it.]

Rusty Pickaxes can only break when used to dig a wall, not when used to attack a monster, so they can make decent fallback weapons, esp. when you're using a Mixer monster to add runes to your primary weapon.

This dungeon appears to offer a wider variety of grasses than normal, and they aren't pre-identified for you, so just be aware of that fact before you go eating all the unknown grasses you find.

[TODO: give more tips for beating the 99F version.]

Open Questions

• What happens if you eat the Gold Onigiri or Silver Onigiri? What happens if you give them to Superspy Deisaku? Can you ever get more copies again? What if you get several copies and replicate them to feed many copies to Superspy Deisaku?
• If a monster normally drops something special, but you have the Gold or Silver Onigiri in your inventory, does that negatively impact the odds that the monster will drop the special thing?
• Does a Gold or Silver Onigiri affect other item generation, such as items pre-placed on the floor or items found in shops?
• What happens if you select either a Gold or Silver Onigiri from the Mountain Lord the first time you meet him?
• What happens when you beat the 99F version?
