What happens


It is possible to die while having the Eirin card and while having at least one bomb in stock. Note that this bug does not work with the Eiki card despite the two cards being functionally similar.

Reimu dying in Stage 3
Figure 1: Reimu dying while having the Eirin card equipped and having at least one bomb in stock.

How it happens


To replicate this, you must die right before dialogue appears while having enough bombs and while having the Eirin card equipped. This is easily replicable on Stage 3, before the mid-boss appearance.

Why it happens


There are several conditions that have to be met for the Eirin card to activate. One of those conditions is for the dialogue to be inactive. Usually, if a dialogue is active the player becomes immune to bullets/entities. However, if the player is in the dying state right before the dialogue becomes active, the death will still happen.

In particular, for this bug to happen the following sequence of events must occur:
Player gets hit -> Within 8 frames, dialogue becomes active (Eirin card cannot activate) -> Player dies
