Blue Archive Ui (Swimsuit) Overview

Character Overview

Ui (Swimsuit) is a Limited 3* Piercing Striker student who will be introduced in the upcoming event “In Search of Hidden Ruins” alongside Hinata (Swimsuit). What makes this banner unique is you are given free 100 pulls, so you will have to choose between S.Ui and S.Hinata. On release, she has proven to be a niche but strong damage buffer somewhat similar to S.Hoshino.


  • Strong damage buff


  • EX Skill reposition can be hard to use
  • Maximizing buff uptime is difficult

Skill Review

EX Skill

Starting things off, we have the bread and butter of S.Ui’s kit, her EX Skill, which increases the team’s Piercing Effectiveness for 45s. This buff also allows you to buff multiple damage dealers, allowing it to fit perfectly in Hypercarry and Multi-DPS teams. Unfortunately, it can be hard to use, as it repositions allies to S.Ui’s Position. On the other hand, this can be used to your advantage to move your team away from an AoE attack.

Basic Skill

Moving on to S.Ui’s Basic Skill, we have another core component of her skillset. This increases the Piercing Effectiveness of all strikers for 30. To activate this skill, you are required to have 3 Clues, which can be gained by her Sub Skill. However, this skill has a steep activation condition which requires you to properly plan your rotation to make the most out of this skill.

Enchanced Skill

If your S.Ui is at 3*, you can completely ignore this skill, as her personal damage output is nothing to write home about. However, Unique Equipment 40 adds a maximum HP boost to this skill, making this skill highly valuable if you are lacking survivability.

Sub Skill

Lastly, for the Sub Skill, this provides her with an ATK boost and 1 Clue when an ally other than Ui uses an EX Skill 2 times. The main trigger condition of the Basic Skill, it is also because of this trigger condition that you are required to pay attention to your rotation. If you misalign your skills, it is possible to gain the Basic Skill buff either at the end of its duration or after the damage window of your rotation.

Gameplay Progression

Early game: S.Ui does not find usage in the early game, as her buffs are overkill for general content. She can be replaced with any damage dealer of the respective damage type or supports, healers, or tanks as needed.

Early game alternatives: Any damage dealer that matches the armor type of the stage you are trying to clear.

Late game (High Investment): For the late game, S.Ui finds usage 3 Heavy armored raids HOD, Binah, and Chesed for Torment. This is mainly due to her strong damage buffs, with decent durations. Unfortunately, she is not a popular option for Insane below as her damage buffs are usually overkill for that type of content.

  • Minimum Required Investment: Unique Equipment 40
  • Skill Leveling Priority: Basic > Enhanced = Sub


Overall, S.Ui is a potent Piercing buffer that finds usage in 3/4 Heavy armored raids. This is attributed to Piercing Effectiveness buffs, which can almost double the damage output of a student. However, this does not come without any caveats, as her EX Skill forces your team to move to her position, which makes it difficult to get everyone in the correct spot. In addition to this, the Basic Skill requires you to pay attention to your rotation or you will not benefit fully from its effects.

How Much Should I Invest?: 3* is usually enough for most cases, but if you wish to improve her survivability then UE40 can be considered.
