Two editorial notes on this batch:

1. Events 2 & 6 are duplicates — both are MITSUBA (7280) announcing the same Ryomo Systems launch, filed on TDnet and EDINET simultaneously. I collapsed them to one block.

2. Ryomo Systems deal has three filers (7280 Mitsuba launch, 9502 Chubu Electric launch, 9691 Ryomo opinion) for a single underlying transaction. If you want a compact view, all three could be collapsed under the target (9691) block with a note listing both co-bidders — happy to adjust the format rule if that's preferable.
