Talk to Hiroko Sagisaka
Travel to Shinjuku: East Shopping District (8 Years Ago) and then head to the Misono Detective Agency. Go inside and speak with Hiroko, who will be standing next to the desk in the back. She’ll tell you about a tip for a lead that she got on social media. Her contact received a strange message instructing them to visit the Akihabara back alleys. This scared them a bit, so they would like Hiroko and company to investigate!
Investigate the Akihabara Alley
Travel to the Akihabara Station: Electric Town South Exit area in Akihabara, then head to the northeastern part of the map. You’ll find the map transition to the Akihabara: A Certain Back Alley area on the right of the medicine shop. Take it, then make your way to the eastern part of Akihabara: A Certain Back Alley area. Speak with Hiroko there to begin discussing the giant toy blocks.
Look for the First and Second Blocks

To find the first block, head east from the group of blocks and look in the parking lot where the taxi is parked. You’ll spot a glowing area in the corner that you’ll want to interact with. Upon doing so, you’ll receive the first block.

Next, head back towards the groups of blocks, but take the next right to go south. Off to the right, you’ll spot a group of parked bikes. Just past them in the corner of the area, you’ll find another glowing area. Interact with it to receive the second block.
Deliver the Blocks to Shota Kuroi

Now that we have both blocks, return to the group of blocks and speak with Shota there to hand over the blocks you found. This will trigger an event where the blocks connect together and ask to play with the group!

Boss Fight – Toy Blocks

For this boss fight, you’ll be facing a Level 8 ToyAgumon: A Rookie gen Vaccine attribute Digimon with the puppet type. It’s weak to Wind and Null-typed against, while resisting Water and Ice. It will also constantly use its Plastic Blaze attack.
- Plastic Blaze: Target: 1 enemy – performs a Null physical attack at power 50 with a 20% chance to apply Confusion
You’ll want to bring some Data attribute Digimon that use Wind and Null attacks. Some good Digimon for this are:
After you defeat ToyAgumon, an event will trigger, leading to the completion of the mission.
