AKIBA'S BEAT (UP)

Story related and cannot be missed.

This chapter has three boss battles, all located in the Digital Delusionscape.

First boss battle is a solo battle with Yamato, and no support. You won't be able to level him up since Chapter 12. The boss can use Imagine Mode, so guard during this phase. Watch your HP.

Second boss battle is immediately right after the first battle, but you are using Saki, Kotomi, and Riyu, though they haven't leveled since Chapter 12. It's a 3 vs 2 battle, so the odds are in your favor. Both bosses here are weak against lightning. After the second boss, you can either leave the dungeon to level up your characters, buy items, and save, or head straight to the third boss.

The third boss is weak to fire. Since you have a full 4 member party at this point, this boss shouldn't be too difficult.
