Asaba Harumasa Best Team Compositions and Character Synergies

Dialyn is one of the best stun agents and will grant Harumasa a massive DMG Bonus as well as a Stun duration extension. She can also trigger Harumasa's Ultimate regularly.

Trigger or Qingyi are very good Stun Agents that can easily create a ton of Stun windows for Harumasa to burst enemies down. Trigger has the advantage to not need as much field time as Qingyi, but Qingyi deals more Daze.

Astra is the best support for attack agents, making her the perfect teammate for Harumasa. Since Harumasa is slightly weak on his own, Astra is almost required for him, since she will grant him a massive boost, and he is one of the characters that gets the most out of it.

Seed and Yanagi are amazing option if you want to play Harumasa without having to play him actively on field. Seed's best teams primarily revolve around having another Attack Agent in the Squad. Harumasa will play the Vanguard role for Seed: you swap him in regularly to use his EX Special, before switching back to Seed who will gain a massive DMG bonus. Yanagi on the other side will not only provide the missing DPS, but also trigger Harumasa's special ability, since she is from the same Faction.
