Blue Archive: Chiaki Guide and Team Build

Blue Archive, just recently released Chiaki’s banner on Global server. Motomiya Chiaki is a 3-star Striker specializing in Sonic-type damage playable character in Blue Archive. She is currently obtainable from 13/05/2025 – 27/05/2025. This analysis delves into her known attributes, skills, and potential gameplay roles. 

Core Attributes and Role 

Chiaki is a Middle position Striker, wielding an Assault Rifle that deals Sonic-type damage. This puts her as a damage dealer, particularly effective against enemies that are weak to Sonic-type attacks. Her defense type is a Special Armor, making her more durable against Mystic-type attacks but vulnerable to Piercing-type damage. 

Chiaki’s Skill Set and Analysis 

EX Skill (Cost 6): Deal 1459-2772% damage to one enemy (this attack can not be a critical hit). 

This is a single-target burst that deals a high percentage of Chiaki’s Attack to one enemy. However, it is mentioned that this skill cannot critically hit and costs 6. This is an important factor to consider when doing damage calculation and overall damage output potential. 

Normal Skill: Every 30 seconds, increase Sonic Efficiency by 32.9 – 63.1% for 20 – 25 seconds. 

This directly boosts the damage of her Sonic-type attacks, including her basic attacks and potentially her EX Skill’s base damage before multipliers. 

Passive Skill: Increase Attack by 14 – 26.6%. 

This passive boost provides a straightforward Attack stat and is fundamental to her role as a damage dealer. 

Sub Skill: When EX skill is activated, increase EX skill damage by 24.7 – 46.9% for 7 seconds. 

This increases her EX Skill damage that amplifies the damage output of her EX Skill. 

Gameplay Analysis and Potential 

Chiaki’s kit suggests a role as a dedicated single-target Sonic DPS. 

Strengths 

• Focused Single-Target Damage: Her EX Skill, despite having no-crit limitation, can deliver a high damage blow to a single enemy, making her potentially useful against bosses or high-priority targets. 
• Sonic Damage Specialization: With Sonic attacks and a self-buff to Sonic Effectiveness, she can excel against enemies that are weak against Sonic-type attacks. 
• Self-Sufficient Buffs: Her Normal and Sub skills directly enhance her own offensive capabilities, reducing the needs to rely on external buffers for those specific effects. 

Weaknesses 

• No Critical Hit on EX Skill: Although having high multiplier, this is a significant drawback as critical hits are major damage multiplier for many other DPS students. This means that her peak damage potential on her EX Skill is capped compared to other crit-reliant attackers. 
• Single-Target Focus: In scenarios that require AoE damage, Chiaki will likely be less effective compared to other DPS students that have AoE damage. 
• Potential Cost Inefficiency: An EX Skill cost of 6 is relatively high, requiring careful team composition and proper skill cycling to be used effectively without hindering other students performance. 
• Competition: The Striker role, and even Sonic-type DPS, can be quite competitive with other students who might offer more utility, critical hit potential, or lower cost skills. Player discussions have sometimes compared her to other single-target DPS students like Maid Midori, debating the trade-off between Chiaki’s non-crit EX Skill and others’ ability to crit.

Team Synergy and Usage 

Synergy 

• Chiaki would benefit from students who can provide general Attack buffs, Crit Damage buffs (even though her EX Skill is not affected by it, it would still affect her basic attacks if they can crit), or decrease enemy defense. 
• Students who can help with skill cost recovery or provide other forms of utilty could also complement her high EX Skill cost. 
• Within the Pandemonium Society, there have been some community observations about potential synergy. For instance, Iroha is a Tactical Support who can buff Attack, and Ibuki might offer buffs that could benefit Chiaki. However, there are also some comments suggesting that some Pandemonium Society students may not have a direct synergy with Chiaki’s Sonic-type damage focus like Makoto. 

Game Modes 

• Total Assault (Raids): Chiaki could find a niche usage in raids against bosses that are vulnerable to Sonic-type damage, particularly if they do not have mechanics that heavily favor critical hits or if her raw, non-crit damage is sufficient enough. 
• Story/General Content: For stages with tough single enemies that are weak to Sonic-type damage, she could be a viable option. 
• PvP: Her single-target, high-cost EX Skill might be less ideal in a fast-paced, often AoE-focused PvP environment, but this can also depends on the specific meta and opponents’ composition.

Conclusion 

Motomiya Chiaki is a specialized single-target Sonic-type DPS Striker with a kit that allows for significant, albeit non-critical, EX Skill damage. Her value depends on the presence of Sonic-weak enemies and whether her consistent damage output can outweigh the lack of critical hits from her main damage output in specific scenarios. While her high EX Skill cost and single-target nature may hinder her universal usage, she can be a strong consideration for players that are in need of Sonic-type damage against single-target focused enemy. Her personality and role within the Pandemonium Society also add to her charm for many players. As with many Blue Archive students, her ultimate effectiveness will also depend on player investment, team composition, and the specific challenges being faced.
