Grea (Summer) is one of the pillars of Water charge burst teams, providing a large boost to charge attack damage and damage cap for herself and one other party member through LinkageGains Grea's skill and support skill effects (Can't be removed) and Dracoforce Under Grea's sway / Grea's ATK specs will be boosted upon attacking this foe (Can't be removed) Local status effect.
Her utility doesn't stop at C.A. either—Linkage grants both her and her target a small heal and charge boost at the end of every turn while Linkage is in effect, helping sustain them through battle and filling their charge bars quicker. Activating DracostrikeTriple attack rate is boosted / Attacks made with elemental superiority have a chance to deal boosted DMG / Supplemental DMG to critical hits will also boost their triple attack and crit rates for two turns at the small cost of Grea's charge bar, mitigated by her aforementioned charge boost.
On top of all that, Linkage has zero downtime: the effect ends the same time her skill finishes cooldown, allowing her to immediately reapply Linkage. This combination makes her one of Water's strongest premium characters.

In longer battles, Anre has powerful damage mitigation and grants a StrengthATK is greatly boosted based on how high HP is buff with his C.A. to boost the party's damage even more.

Vajra: Vajra is Grea's ideal partner in Bonito teams. Vajra, like Kengo, has a 200% maximum charge bar and would appreciate the charge boost from Grea's Linkage effect, especially since higher stacks of Loyalty EternalATK is boosted / DEF is boosted / Charge bar speed is boosted Can't be removed speed up charge bar gain.
Gwynne: She should act before Grea. At level 45, she gains access to Guns and RosesConsume 1 Burst ShellConsumed upon using Guns and Roses (Can't be removed) to deal 3-hit, 100% Water damage to a foe (Damage cap: ~215,000 per hit).

Cue Grea's double CA.
This build is centered around maximizing Charge Attack damage. Therefore, prioritize C.A. DMG and DMG Cap, followed by Water ATK, and then multiattack nodes.
